I think I'm going to throw up every day (anxiety)

I have a very severe fear of throwing up. It terrifies me to no end. I've only thrown up 4 times in my life, once in 7th grade and the rest before age 7. I'm 18 now. I have anxiety and OCD and every single day I get thoughts that today is going to finally be the day I throw up and that I won't be able to escape it. Of course I've yet to actually throw up from these thoughts or have them come true but it doesn't make them any less scary. I don't know what to do, it's making me afraid to go out and to do anything aside from lay in bed. It's actually terrifying. And no, I'm not going to "just throw up" to get over it. Nothing seems to convince me that I won't throw up, and I think about it at least once a minute if not more. I always feel so stressed, tense, and on edge waiting for the day to come where I actually vomit. I get nervous that I'm getting too anxious and that the anxiety will make me throw up (even though that's never happened to me). I want my life back. 

Please help me :(
