Eating Disorders:

I'm sorry you're going through a stressful time!

Not something I usually talk about, but when I was a freshman in high school I had eating issues. I made myself throw up. I found out later that it was for the reason you described, it was the one thing I could control. It made a lot of sense to me. I think that's exactly what is going on with you. Stress really goes that way or the other though. People either don't eat for the control reasons, or they eat more because it comforts them. Food is instant gratification, especially sweet food. It's like people that drink. It makes them feel better in the moment because they feel so cruddy, but it doesn't solve the overall problem at all. But you could have some type of depression as well that might be the reason. Depression causes you to lose interest in things, and that includes food. I would maybe check into that as well.

I hope things get better for you!
