I have a problem when i like someone, i always feel sick. Then when i actually start to date them i am vomiting every morning and i dont eat much at all, probably a sandwhich a day. This makes me tired and ill and i look awful. I can't enjoy myslef when im going out with them because i am so nervous and feel very sick all time. I end up breaking up with them because i can't cope with the stress of it, the sick feeling usually goes on for about 2 months where i vomit every morning. What should i do?
