Hi alex!
I know about the fear it causes, I have also lost my period, I haven't had one since January...it's a scary thing. You SHOULD see a dr. asap, like others have suggested. I honestly don't know what damage is causes, but I know it's serious. I haven't told anybody about my ED, so going to a doctor is still scary. We're all doing such harm to our bodies.
Let us know how you're doing! And it's great to hear that you're starting to eat again!

that's a big step, a hard hard FIRST step! I admire your courage!!!
NEVER GIVE UP
