125 is not big hunny it is in fact very normal and healthy! You should really try not to make goals for yourself like that because if you get down to 110 you will want to keep going and making new weight goals for yourself... I know because i was pretty much in the exact situation you are. It is not worth the struggle sweetie i promise. Your healthy life is so much more deserving then your life with and eating disorder.
I know i am not much help. But I am here. And I care. So pm me anytime
