My life has been a constant battle with food. I see something I want any my brain screams "No!" I look at my 5foot 3, 95lb. frame in the mirror and some how I'm still disgusted.
A little over a year ago I met my 'wonderful' boyfriend. He was supportive and he cooked the worlds most irresistible Italian food. I finally felt comfortable. I felt like he would love me no matter what I looked like. And I started to get better. Eventually I began to see that my lack of food was affecting my health and made the decision to eat even if I didn't want to. I got to the point where eating became an enjoyable experience instead of the most dreaded part of the day.
About a week ago I found out that this 'wonderful boyfriend' has been having sex with my neighbor the entire time we've been 'together'. My confidence is shot.
Food has once again become the enemy. I hate eating. Everything tastes bad. Still I know that I am too thin to be healthy. Mentally I know that I need food and that my weight had nothing to do with my relationship.
My body seems to have other ideas though. I have never been bulimic, but now even though I can force myself to eat with only minor discomfort....I cant keep anything down. An hour or so after I eat I feel horrible and then I just throw up out of nowhere! Most of the time I totally forget that I ate until I throw up. Still I wonder if somehow my brain just doesnt want food....

You're not making yourself throw up if it seems to come out of nowhere. If you were bulimic, you'd be consciously making it happen. While you do seem to have some problems bordering on an eating disorder, this doesn't sound like actual bulimia.

More likely, there's something physically wrong that's making this happen. In your other posts, you mention symptoms matching ovarian cysts or possibly appendicitis... these conditions can certainly cause nausea and vomiting. There could be any number of other things wrong as well. If you haven't seen a doctor about this, do.

If no clear physiological cause can be found, it's probably the breakup making you sick (and is this the fiance you mentioned in a previous post?). Severe emotional distress can cause physical symptoms like this. If you associated the enjoyment of food with this relationship, all the more reason why its end might cause this.

Don't blame anything that your bf has decided on yourself. It's NOT your fault - just his horrible decision.

It sounds as if your anorexia and GI upset is secondary to the other stressors going on in your life. You need to focus on these first in order to help yourself. I agree with GreenTea - it's not quite bulimia if it's not self-induced. Your body may just be rejecting food as a way to cope with stress and anxiety.

If you need someone to talk to, we're here! There's also lots of great websites and hotlines out there that may help as well.

I agree with everyone else. I was in a relationship for over 10 years and then out of nowhere found out he cheated on me over a year ago. I also had a difficult time eating afterwards and I'm not anorexic, but I'm 5'-5 1/2" and 95 lbs. You have to tell yourself you are better than him. It took me about 1.5 months to feeling better. Also be happy it's now and not after having 2 kids like we both have.
