Unfortunately thats how any form of therapy works - the therapist cant fix us we have to do all the work ourselves - come up with what help and what doesn't help and do what does help. I used to have a fear of getting sick from mayonaise. I got past it by using it in extremely small amounts at a time and slowly as it didn't make me sick I would increase it. and telling myself that I was now an adult with an adult stomach that if I can handle other foods I can handle a minute amount of mayo. Instead of mayo I also bought mricle whip that has a tangy sweet taste to it instead of the mayo taste. Now I can eat mayo but not very often but atleast it is now based on taste not my fear of getting sick from it.

Hang in there.
