I am relapsing?

I unintentionally puked tonight after a couple of beers. I feel so embarrassed. I barely drink anymore. Maybe once a week. I go home early.

However, I didn't let myself eat dinner because I knew that I would be trying coffee drinks for my new job. I feel that now that I've puked, I have no release from what I'm feeling. At work, I eat things that are rough on me (I have trouble with fat and sugar and am lactose intolerant).

I've been a bit more restrictive with my diet because I'm going to be in my underwear on stage for a play.

I just fear that my diet may be affecting my digestive tract. I honestly am horrible at gauging wether I eat enough or too much. It's always too much in my opinion. I have a high metabolism, so I always feel like I eat more than others.

But for some reason, I keep telling myself to skip eating for a couple of days to lose weight and then reminding myself that I have had problems from fainting spells from not eating too much. I just want to slim down my tummy.

Am I OK, or am I overreacting? It seems like every time I slip back into a relapse, I never see it so I am trying to be careful.

Am I OK?
