Hey there,
 
Weight doesn't make up who you are, at all.  What matters is what's on the inside, and you never fail anybody.  And as far as your boyfriend goes, I believe he's telling the truth, I know you are a beautiful person, inside and out.  And people do love you.  You are loved more than you think you are.
 
And about the eating disorder, I think it depends.  Most people over-eat at some point in their life.  I over-eat all the time, but that doesn't make up who I am.  But many people who do, don't have an eating disorder. If you are really worried about it, I recommend you talk to a parent, a close friend, or maybe even a teacher at school...somebody you trust that will point you in the right direction.  
 
PM me anytime.
 
Always,
 
Liz
