(((hugs))) you will find that you are never alone here..... Do you have a therapist or a counselor at your school you could talk to - you don't mention whether it is college or not... sooo... I' m a little concerned...

For me, I did the reverse, I replaced the eating disorder with the SI for a while...neither a good option!!!
It sounds like that maybe you are using the food to relieve the stress??
When my stress gets out of control - that is what I do...it is what I've always done... it is what my particuliar "trigger" is...
The "trigger" is different for everyone...

But if this is the "beginning", seeking professional help
right away would help alot...

((((huggs))) freewill
