I really need help with this...it affects my life so much?

I think I suffer from emetophobia, the fear of throwing up. Whenever I get a stomach ache or feel sick, I'm scared I'm gonna throw up. This results in me getting hot and clammy and having anxiety attacks. I try to deep breathe but it's very hard for me because the attacks come on at random times: school, in the car, parties, wherever. It's very embarring and people think I'm a freak when I say that I'm "nervous." Does anyone know of any ways that can calm me down? Maybe there is someone out there with the same problem as me. Thanks!
