My biggest advise is BE CAREFUL.

I started anorexia from being sick. I'd really wanted to have the self control to quit eating but my stomach always hurt so bad when I wouldn't eat. Then I got the flu and it got me past the first few days of stomach pain from not eating. Once the hunger pain obstacle was out of the way I could not eat and feel ok.

If you are concerned I would talk to your doctor about it. They would probably have some tips on what to eat to get your stomach adjusted to eating again and help keep you accountable so you don't quit eating.

Just be careful.

I hope you feel better.
