Every time I try and eat I feel like I'm going to throw up. I feel ravenously hungry all day but can barely stomach food. Sometimes I throw up but usually I just get waves of nausea, my heart beats really fast, I can't breathe and I have to close my eyes and 'shut down' until it goes away. Then I give up eating before I throw it all back up. I feel really ugly and skinny and losing weight upsets me, I'm not sure whether the pressure I feel to put on weight has something to do with this as it's making me anxious or something. Or if I have a medical problem of some sort. Has anyone else had this experience? I understand it's very different from anorexia etc - in fact, it's the opposite. I struggle with compulsively checking myself in the mirror, weighing and measuring myself because I so badly want to be healthy and curvy and not thin.
