panic attack advice please

I am freaking out right now, I'm terrified of throwing up and my boyfriend thinks he has the flu. I asked him to leave and he completely understood. Now my brain is convincing me I'm going to puke and I'm in a full blown panic attack. Can you guys please share your methods of handling panic attacks💕💕💕💕💕 I figure this post can help myself as well as others who go through anxiety and panic attacks :)
