Eating and Nausea

I've had issues with food since, like, forever.  My earliest memories were of me vomiting, and the memories are very vivid, even though I was barely 3 years old.  I remember the smell, texture, look of it, and because it's something scary you are not in control in it's a horrible experience for me.  Because of that I will not eat anything I've been sick with, which so far is rice pudding, beef stew, sweetcorn, ham and coleslaw sandwiches, rice, and stuffed chicken.  My whole life seems to be revolved around sickness.  With the way my brain works if I'm sick for a certain reason, or someone else is, I automatically think that's how it will happen again.  Because I get anxious a lot anyway around people and being certain places this in turn gives me nausea, and then I think I'll be sick, which makes me more anxious.  Viscious circles!

I've avoided everything from social gatherings to evenings out just because of sickness.  I don't like being a car passenger and I won't go on fairground rides because people are sick on these things so if I don't do that then I reduce my chances of being sick.  But, with having nausea a lot it puts me more on edge and I'd rather be using my brain space more for reading about chemistry and learning more periodic table stuff.  I've told me doctor I really want more CBT as it's helped me before but all she wants to do is give me medication, which doesn't stop the thoughts.  Only masks the anxiety.

Does anyone else have similar issues?  Or, issues with nausea with anxiety?  If so how does everyone else cope with it?
