Ooh! Here's a few favorites of mine. Some are angstier than others, but all have happier endings :)
* Busy Being Born (http://archiveofourown.org/works/479492): In 2210, most of the known Galaxy is part of Colonial territory. Society has advanced far beyond its keenest dreams, but male Omegas are still treated as basically worthless and hidden away by their families. For the longest time, Dean Winchester thinks he is just that: a useless Omega whose only purpose in life is to keep his uncle Bobby’s junk-freighter working while his father tries to find the raiders responsible for Mary’s death. But anything changes after Dean, desperate and unhappy with his existence, tries unsuccessfully to kill himself – suddenly he has to face a new world far away from his father and uncle, a new group of people who want only the best for him, but most of all, he has to come to grips with the fact that he has never truly been an Omega but a subdued Alpha all along. (Angsty but worth it)
* Do or Do Knot (http://panacea-kiss.livejournal.com/1240.html): Since puberty, Jensen has spent his life hiding urges and a physiology that society finds unacceptable. He may not be the only one hiding urges, however.
* Overdue (http://archiveofourown.org/works/2310353?view_full_work=true): Jensen is a lonely omega who works as a librarian in Austin, TX. He spends his afternoons reading aloud to the local elementary school kids, wishing that his life were different and that he could have a child of his own, but its just not possible. He befriends Jason, a sweet bright little boy who loves to read and seems just as lonely as he is. Then he meets Jason's father, Jared, a handsome alpha who spends too many hours working at the hospital and, in Jensen's opinion, not enough time with his son. Jensen confronts him about it and they have words, Jared telling him in no uncertain terms to mind his own business. Jensen writes him off as a major prick, which is why he's not at all happy to see him at the library again the very next day - especially since Jensen's heat picks that moment to hit him hard. Jared steps up to help him through it, and as they learn more about each other he gives Jensen reason to hope that maybe the things he wants most aren't so far out of his reach after all. (Contains mpreg)
* Cousins (http://archiveofourown.org/works/1006740): It's Christmas and omega Jared Padalecki, 18 years old, is bored out of his mind at the annual family gathering. He never expected that his life would be changed forever when an older cousin he's never seen before is introduced to him.
* Yes, Chef! (http://archiveofourown.org/works/3199079) The way to an alpha's heart is definitely through his stomach. Omega Jensen may be young, but he's well on his way to being one of the best omega chefs out there. Now if only alpha Chef Padalecki would acknowledge that omegas were tough enough to handle the heat of his kitchens.
* No Substitution (http://blindfold-spn.livejournal.com/3417.html?thread=4617561#t4617561): [Requires joining LJ blindfold_spn community to view] See, the problem isn't that Jared's an Alpha. Hell, the industry is fucking full of them, both in front of and behind the camera. Jensen knows how to handle the overinflated sense of entitlement from knotheads just fine, can weather the heated, hungry looks constantly thrown his way with little care. And yeah, so he's gotten into a few scrapes here and there with guys who made the mistake of pulling their macho, dick-first bullshit on him. But he's always come out on top, in a manner of speaking. He's held his own. No big deal. The problem is that Jared isn't like other Alphas.
Ooh! I've got some :)
