I hope someone can help me with this, i can't do this anymore

Here a little bit of background. Ive developed emetaphobia from a bad tummy bug last christmas when I was 7 months pregnant and had panic attacks day and night for a whole month (not realising it was an underlying fear of being sick again) but now I know it is. Anyway, I've been steadily making progress and can get myself out of that panic feeling quite quickly but we went away on holiday (only an hour from home) and one night I had a big meal which made me feel sick and because I was away from home it really stressed me out and I started to shake convincing myself I would be sick again. We only stayed that night and went home the next day.

So now that I'm back home I still feel anxious. So much so that I just can't eat Anything that's not "safe". I can eat a small bit of cereal, bananas and Yoghurts. The look of anything else turns me. I have to eat very small portions so I don't feel overly full up. Ive lost alot of weight over these few months and even more so this past week (I lose weight and put it on easily).

I'm just so fed up.. I can't not eat proper food because when I don't eat enough I feel dizzy and sick!! I can't win.

I've tried taking kalms which are ok at relaxing me but I still can't eat a proper meal, what can I do? I have a doc appointment on Thursday but can't starve til then. I also have a CBT book which was very helpful but it means facin my fears and just eating and dealing with the full up sick feeling.

I don't know what I expect anyone to say but I just feel so scared.
