Tommorow im going out with friends and since morning i've been feeling my heart beating really fast and also a feeling that I could throw up at any time if I cough even more, and breathing doesn't help much, just makes me cough even more usually. Last week I also went out but threw up 3 times before going outside and barely held it in and didn't throw up in public. Im just incredibly tired of throwing up and feeling anxious for no reason, its like I can't stop the fight or flight feeling, even though my brain knows going out with friends is fun and there's nothing to worry about, my heart just refuses it and keeps me on panic mode... What do I do...
