What to do?

I do not understand whats happening anymore. First of all I am in love with someone I shouldn't be and second of all my best friend is scaring me.
Most of all reasons I am soo stupid and never get anything!
I am in love with Mr.Russel. Whom teaches me English!
He is twenty seven and I am fourteen also my best friend Emilie loves him too but I don't really mind. Because I love her to bits, she is one of my worries....
She thinks she's really really FAT but she isnt she's Healthy unlike moi.
But she has stopped eating and her mother is accusing her for being bullied which she is not.She mentioned somewhere that she gets hit* but too tell her the truth I do too but they apologies that is if I make them really Mad!!!!
I never wanted to tell anyone how they......But I guess I can confide in you.
She has changed a little from what I knew her since last year she likes Alternative and Rock.
What she use to like was Miley Cyrus but now she thinks she's a ****.
I don't really care much about Disney celebs anymore their just to mundane and they do everything to try to get into the limelight for their stupid rumors and stories.
The thing that upsets is that she can't confind in me anymore, she thinks its okay not to eat, I am being a total Hypocrite but I love her!
I want her too eat, be HAPPY! she is going to France on an exchange on the 14th of March I don't want her to go. She wants to and its her choice and I can't do nothing about it she will be HAPPY glad about that I guess I can endure nine days of Isolation.I think anyways!
I want her to cut down on the sad music and laugh more!
I heard her mother say she has changed on the mic when we were having a conversation on msn.
It kills me that I cannot please my BFF make her laugh BE a good BFF she deserves better then me MUCH BETTER.
She deserves Sibi and Grace she seems her infront of them which angers me that I cannot possibly make her feel what they can their ironic,nice and my friends too but I gotta admit I am envious!
God hasnt been much forgiving so therefore I don't know if I should believe in him anymore!
I wish someone could help me if only someone could tell her show her she isnt what she think she IS.
If only Mr.Russel or Adam Levine{lead singer of Maroon 5} would say something to her!!!!!!
I love her..........
I hope she's OKay!
That is all for now anyways...............
