The more I reread her posts, the more my heart breaks for this baby girl.
All she wanted to do was go back to Fremont. She really had no "real" friends at school, she was dying to see her old girls, she said she "couldn't deal with all this moving".
That there was never any "starting over" or a "fresh start"..."no matter where I go or what I do, the PAST always follows me."
Feb 9th - wasn't supposed to move...the move is not a fresh start. Basically just a new school where don't know anybody.
She posts she loves her dad...she'd be happy if she were with her dad...mom trying to convince her MH is better than Fremont.
Theres a few things, though...Feb 20..."the worst feeling is you could have stopped something if you weren't so stupid"
Then, not word for word, but Feb 23...basically glad that her sis and dad tell her they get a bad vibe from someone and they're right.
And, that she should have run away - she says "I'm dumb" - BEFORE they moved to MH.
She never mentions anything about therapy, though, but she DOES says "this" is her mom's fault...or "she did this to me".....
OH, and JDB, her dad's GF lives in S.F. if that might help your theory, it's not LA like you believe, but maybe it'll help play into what you're thinking???
