Terrified of throwing up.

So I'm currently more hungover than I've ever been, because I usually pace myself because I'm terrified of throwing up. All day I've been on the verge of throwing up and every time I start to get a panic attack and then the feeling goes away for awhile. I really do want to throw up because I feel terrible but every time I get close my body freaks out and I physically jut can't. It's always been like this but never this bad.

I know throwing up isn't that bad, ive done it before, it'll make me feel better, etc. But I'm still really fucking scared. I'm at a friends house and I'm scared that they'll make a big deal out of it and I hate unwanted attention or I'll gross them out or something. I don't know. I'm just frustrated. I can't do anything except lay down when I feel like this.

Looking for advice or anything really, sorta needed to rant too.
