I really hope you are feeling a bit better today. My friend was just like you three years ago. She had struggled with IBS and literally became afraid to eat - and doctors just kept saying she was anorexic. She did get over it though - the other day I went round to her house and found her tucking in to a tub of ice-cream!!!
Personally I find that I become so scared to try something new it actually makes me sick even though there is nothing in it to act a trigger. Hence an all night panic attack once because there was a tiny bit of cocoa powder in something!!! If you think it is going to hurrt, it generally will, as you tense up and clench your stomach. I also find I can con myself into eating by going for a walk and eating on the run so to speak - there's nothing worse than staring a a bowl of food feeling like you are going to throw up, so this provides a distraction.
Is there a reason you can't eat bananas - they have been my complete life saver (I am IBSD/pain). I find they are the only things I can tolerate in the morning.
Give the therapy a chance - you might need other help as well though. You are bound to be feeling low just because this is a miserable way to live for so long.
Please, please, please take care - or I will be forced to send you sewing kits across the atlantic to cheer you up!
