Abused!Jared fics:
Bring Me To Life (http://ally-fics.livejournal.com/10338.html) Jared’s a shy young man, whose life has never been easy. His father hates him, his mother drinks her sorrows away and his husband Paul treats him like he is nothing more than a beautiful toy. When his husband has to go away on a business trip to Europe for two months, he sends Jared away to a ranch in the middle of nowhere to keep him under control. There, Jared meets people who show him what love, friendship and loyalty mean for the first time in his life. Can he escape his life and finally find some love and happiness for himself?

Shouting Out Loud (http://blynnk.livejournal.com/30918.html) Jensen and Jared are college students who are nothing alike and meet for the first time when they both enroll in an acting seminar. They are cast as the leads in an experimental 2-man play dealing with domestic violence.

The Three Faces Of Jared (http://www.sinful-desire.org/archive/viewstory.php?sid=2500&warning=5) Meet Jay Welling. He's married to a very rich man, living in a beautiful home. To the outside world he appears to be a withdrawn but sweet young man. To his husband, he's a prize. But deep down inside there's more to Jay, and 'they' are coming out. When Jensen meets the beguiling young man, he's not sure what to think- but he knows he wants him.

Addict!Jared:
Live To This (http://truelyesoteric.livejournal.com/94011.html) When they first meet they’re just two screwed up people looking for something. It’s only supposed to be a one night stand, but they just can’t shake what they found in the dark. But everything between them blew up in their short time together. Years later they’re even more screwed up and they’ve stopped looking for anything. But what was once there is still there.

The Incremental Breakage Of The Last Tenuous Strands (http://smash86.livejournal.com/57253.html) Sometimes there is friendship and sometimes there is love… and sometimes you have no clue that you have fallen heart deep into someone’s soul. It’s only when you break apart that you realise you are trying to hold onto something that does not belong to you. Jared loses his girl, his family and then himself when he realises the only thing he wants… the only thing he will never truly have is Jensen. He spirals into despair and drugs and Jensen, deep in his own denial of this thing between them, does not see the intensity of Jared’s destruction until it is nearly complete.

Jensen Humiliates Jared
The Dog Game (http://annie-46fic.livejournal.com/28626.html) Jensen Ackles and his crowd are rich and privileged. They have never faced any challenges in their lives and have to come up with their own way of amusing themselves. The invention of the cruel ‘Dog Game’ keeps them on their toes but do they ever stop to consider who they are actually hurting? When Jensen chooses the wrong person to enter into the game, his life takes a direction that will change his views forever.

Thank you.
I haven´t read number 4 and 5

Oh, this is my all time favorite category. :)

We Were Here (http://j2-wewerehere.livejournal.com/1579.html) - AU J2 This one is haunting and sad with lots of hurt for both boys, but the comfort is gorgeous when it comes. There's a sequel and a couple single scenes, too, if I remember correctly.

Flightless Bird (http://foolsdance.livejournal.com/9291.html) - AU J2 This is a slave!Jared fic with lots of oblivious but protective!Jensen. Nice happy ending.
a
A Lesson a Day (Could Kill You) (http://www.sinful-desire.org/archive/viewstory.php?sid=2329&warning=5) - AU J2 "Jared has an abusive past, and when his boss sends him to learn how to become a flair bartender, that past is brought back in a storm of pain when he falls in love with his teacher, Jensen. But Jensen has his own problems and soon their attraction causes nothing but trouble, especially when Jared tries to face his fears."

Falling Forwards in a Backwards Land (http://queerly-it-is.livejournal.com/2889.html?view=387401#t387401) AU J2 - pornstar!Jared with a stalker. Hot and angsty and cute.

Hooker!fic (http://epicallytired.livejournal.com/239671.html) - AU J2 hurt!hooker!Jared and protective!Jensen

Fire in the Hole (http://insane-songbird.livejournal.com/183142.html) - J2 "At seventeen and growing up in a white supremacist camp, Jared's life is going nowhere fast. He doesn't feel like he belongs, but sees no way out - until the arrival of a new member shakes things up in the paramilitary group. Jared doesn't know whether he should be intrigued or afraid of Jensen Ackles, but when he gets caught in the power play around him coming to a head, he's left with little choice in the matter."

Who Watches Over Me? (http://archiveofourown.org/works/396200/chapters/651307) - J2 bodyguard!Jensen and moviestar!Jared with a stalker. This one is a little more Jensen-focused, but there's still lots of Jared and delicious man-on-man action.

The Ballad of the Invisible Boy (http://archiveofourown.org/works/1017905) and Two Headed Boy (http://archiveofourown.org/works/1997235/chapters/4327308) - S/D Oh my god, I just finished this one today (it's very, very long), and I think it might be my favorite Sam/Dean story yet. So much delicious angst, and such a gorgeous happy (finally) ending.

Cicatrix (http://askellington.livejournal.com/15633.html) - AU S/D This is a really creative world with convincing characters that are fresh yet remain true to their original essences. Love protective!Dean in this one.

Worth the Price (http://samdean.archive.nu/viewuser.php?uid=992) - S/D Another long fic with agonizing amounts of hurt for both boys (may be too much if you're looking for happiness, but the happy ending is there and worth the slow build).

Further and Further Out (http://samdean.archive.nu/viewuser.php?uid=992) and Rearrange Me 'Til I'm Sane (https://www.fanfiction.net/s/3956847/1/Rearrange-Me-til-I-m-Sane) - AU S/D (boys are still hunters) I just love the boys in these stories. So much hurt!helpless!Sam and protective!Dan with asshole!John (not abusive). Creative story and she writes so beautifully.

Full Moon, Fast Cars (https://www.fanfiction.net/s/3247697/1/Full-Moon-Fast-Cars) - AU S/D (boys are not related) These are great and so much fun. Love how neither boy is weak, but there are definite strong hurt!Sam/protective!Dean elements. This is the first story in a series.

Us and Them (http://archiveofourown.org/works/1765843/chapters/3777526) - AU Sabriel The hurt elements here are more emotional than physical, but this is the story that turned me onto protective!Gabe and Sabriel in general There's a WIP sequel that I'm avidly following. Sam is a tattoo artist and Gabe bakes pastries and c'mon, that's hot.

The Long Way Home (https://www.fanfiction.net/s/3879595/1/The-Long-Way-Home) - AU Gen Poor Sammy is hurt here in all the ways, but what I love the most about this story is the combination of protective!Dean with hurt! and badass!Sam. It's long with an equally long sequel.

Sure Got a Dirty Mouth (http://archiveofourown.org/works/411362/chapters/682610) - AU S/D This is really long WIP that I'm going to recommend anyway because it's just that good, maybe the best protective!Dean I've ever read. Since it's not finished, I can't guarantee a happy ending, but the happy moments throughout are strong enough that I have no doubt. :) Also, if you like Wincest, this one is HOT.

Give Thy Thoughts No Tongue (http://queerly-it-is.livejournal.com/2889.html?view=387401#t387401) - AU J2 Maybe not the best for your request since the hurt is minor and purely physical, but it's a great story anyway so I'm going to recommend it. :)

No Fortunate Son (http://www.sinful-desire.org/archive/viewstory.php?sid=2326&warning=5) - S/D Sad!Hurt!Abused!Sammy and Protective!Dean out the wazoo.

There's also one I can't remember where Dean is possessed and forced to rape Sam, with lots of long painful recovery for both boys. I'll see if I can find it.

Oh, the one I was thinking of is Passenger (http://supernaturalfic.livejournal.com/1615665.html) and With a Spit and a Prayer. (http://sn-fic.livejournal.com/540964.html) Very dark but good ending.

Thank you for your rec. There are some I haven´t read.

Here, this one is extreme abuse but has a really great Happy End: http://archiveofourown.org/works/1167284?view_full_work=true

That sounds great and it is looooong! thank you

"Garbage" (http://archiveofourown.org/works/1811662/chapters/3887857) by Compo67: Jared is a shy, reclusive fourteen year old omega who lives day to day, surviving the best he can. With the encouragement of his school librarian, he reads extra books for fun, preferring to live within the stories he reads instead of his actual living situation. His current book is Mary Renault’s WWII, gay classic, The Charioteer. He is captivated by the relationship between the three central characters—Laurie, Andrew, and Ralph—and the novel becomes integral to his survival. A few weeks before the annual dance, Alpha Detective Jensen Ackles, from the Department of Omega Care, visits the high school and notices Jared by the way he holds his backpack. This seemingly casual observation launches an investigation that irrevocably changes everyone involved—for better and for worse.

this is incredibly beautiful and incredibly harrowing, with an ultimately hopeful and happy ending. made me sob like a baby, which no other fic has done--it hit close to home, though.

I haven´t read that one, but I´m looking forward. Thank you
