Advice? Panic attacks

I had my first panic attack 1 months ago. Most likely because of a long period of stress and childhood PTSD.

I can't leave my house. I am constantly dizzy, numb and terrified. I do go outside, but I quickly return home when I feel like I can't take it. It never ends, I'm like this all day long.

I calm down my breathing and I remind myself that I'm not dying, that I'm okay.

Atarax makes it worse. Started with a SNRI (Venflaxine) medicine, it makes things worse and I just had a panic attack from standing up from my bed (I woke up scared).

I don't know what more to do. Does anybody have a medicine to recommend? Or any other advice?
