Welcome to PC.
Nobody here can diagnose you, but what you're doing sounds troublesome to me, and I assume it is to you as well to be posting here... Do YOU think you have a problem?
There is taking a crash diet too far that won't necessarily lead to the criteria of having an eating disorder... but then anything can progress and cause you more pain in the long run.
Have you talked to your doctor or someone you trust about this?
