i'm looking for these movies?

i've been wondering about this two movies can you me what are the titles?

the first one is about a girl, i think her mom was famous but she was addicted to drugs and was later on arrested. the girl was put through foster homes, the family that first adopted was good but i think the father/boyfriend was sexually abusing her, then the next one was to this rich woman who was going to legally adopt her but instead killed herself... i also remember before the movie ended that she has these boxes/ or small treasure chest that she keeps memoirs from each foster home...

the second movie was about this girl also who kills all the guys that gets interested or attracted to her mother because she just wants them to be all alone.... just the two of them

i'm sorry for the trouble but thanks for helping....
