I'm glad you took the step to go to the hospital. It sounds like your anxiety was really high.

I found myself in a similar situation before I was diagnosed. My anxiety was so high I couldn't eat. I lost 30# in 3 weeks.

After I was diagnosed and things leveled out for me I researched what had happened. What I learned is when you have that level of anxiety your body is producing a lot of adrenalin, going into fight or flight mode. While there, it shuts down systems that aren't completely necessary, one of them being hunger. With the high level of adrenalin and your body using any body fat and muscle for energy you lose weight.

Glad you're feeling better.
