I don't know whyi do this or what it is, i have been talking to these 3 guys for 2 years now and when ever I think of them and see them I start to feel sick after a while. Twice I have ended up vomiting because of this on the same day, and I can't eat when I'm with them without feeling sick. Pleaasse help!! I hate this, I don't know what it is, how can I help prevent this? Maybe its nervouness?? I don't know??
