hellooo... this is my first post in this wonderful community... please help me find the following fics...

1) "A girl makes a deal to bring back Sam from hell, I remember a scene where Dean cas and sam come across this girl at a bar singing and are impressed by her voice... i dont relly remember but i think dean is staying with lisa but i am not sure, they also find out later that this girl is half human/demon and half angel, sam gets extremely angry when he finds out about it" I know its vague but please help me...

2) "In season 5 Sam plans to commit suicide and Chuck informs about it to Dean through a mail, cas brings sam to Dean, Sam assumes Dean to be Lucifer..."

3) Stories from season 2 where Dean ignores Sam and says hurtful things to him but later feels guilty about it

4) stories where Dean decides to stay at sonny or where dean and sam are seperated and when they reunite sam is a changed person, he is emotionally withdrawn, Dean tries to connect with sam and tries to make him the old sam

5) john blaming sam for mary's death and is emotionally abusing him... dean finds out about it maybe in season 2 and later and hates john for it...

5) stories with guilty dean and hurt sam

i prefer only general fics, no slash fictions
