Anxiety attack. Need help calming down

Hello everyone. This is my first time being on here. I am having a severe anxiety attack right now over my emetophobia. So I’ve been struggling with stomach problems the past year now. And that doesn’t mix well with being an emetophobe. I get pretty bad acid reflux, but I think it’s from anxiety, and then I get worse anxiety when it happens and it just goes in circles. Last weekend I went to a concert with my boyfriend and we had to leave early because I had a panic attack and felt like I was going to tu. I feel so bad for my boyfriend because we have had to miss out on so much because of my phobia and anxiety. So when I have an anxiety attack, my chest and armpits get really hot, my heart races, I get bad acid reflux, I feel like something is stuck in my throat, and sometimes I have esophageal spasms. I guess I really just needed to come on here and rant because I feel so alone. My mom doesn’t believe in the phobia. My boyfriend does his best to understand and he is so comforting, but I feel like I need to talk to someone with the same phobia as me. And does anyone else get like literal heat waves through their body when they are having an anxiety attack?
