Can never finish a meal

So I have struggled on and off with anorexia nersova and bulimia for a couple of years now, contradictory i know.

But recently, I have not been able to finish any food, no matter the portion size; I just suddenly get disgusted and nauseated and end up only taking a couple of bites.

I have been wasting food, I hate wasting food, I can't do my boy Sanji like that.

I seriously have no clue what is happening, i dont see my doctor for 2 weeks, any advice or insight?
