Hi, I got a problem that I'd be happy if just a name could be associated with it if no advice can be given.

Basically when I'm with a girl I like, I usually get ill. Its usually at its worst when I'm with a girl I really like in public, especially if other people I know are there with us - I do end up vomiting (although I have enough warning to get to a toilet). I'm usually okay if it's just me and a girl but if I really like them and we get onto a certain topic (the obvious topic), I end up being sick also. I don't think its a sexual problem because I've been with girls before (recently) and had no ill affects thought obviously no one was around and I wasn't crazy about them. Really liking someone seems to make the problem a million times worse.

This is really having an awful affect on my social life so I'd really appreciate advice or a name for the condition so I can get some advice elsewhere. Is it worth bothering a doctor - can they help?
