Panic attacks

What helps you through panic attacks? Mine usually come as me chocking so it makes me gag, sometimes I feel like my mind provokes them became if I don’t think about them I’m okay. I have an actual fear for them because of how bad it feels & how embarrassing they are if other ppl happen to see me having one. It makes me anxious to even go to my appointments, I can’t imagine if I was to be having morning sickness & having to go to my appointments, my anxiety would be at another level
