How do you calm yourself down in panic attacks?

li

My panic attacks are getting pretty severe and they make me feel so sick. The Zoloft clearly is not helping that and I had a weird moment last night with memory loss and just not doing well on it.

I have Xanax prescribed to me but it makes me sleepy and I don’t want to take it. So I want to know how other people calm themselves down from panic attacks. I feel like I’m going to spontaneously combust right now.

I’ve been trying to sit down and cool myself with a fan and just breathe but it feels like my core is shaking and I have no control over it
