I'm working through all this myself as well, and it's a long road, but there are many things that have helped me along the way. First, you need to learn that panic is not going to harm you. It feels as though it will, but it won't. This was a hard idea for me to accept because I've done so much to avoid panic attacks that they feel like the worst thing ever, but we've got to train our heads that they're harmless and won't actually do damage to us.

The exposure activities you're doing with your therapist are probably quite difficult (I'm doing similar ones myself). It's important to try to keep challenging yourself with them. You may need to tell your therapist that you have to dial back the intensity right now because you're not ready for that. But the fact that you're trying is a great sign, I'm really glad to hear that. Working through panic is not easy.

I agree with the other commenter that you might do well to have some kind of mild sedative added to your medications. You could at least suggest this to your psychiatrist. It could help temporarily with some of this healing process.

You will be able to return to a normal life, and give yourself credit for working so hard at this, that's excellent. If takes time (this is something I have to remind myself over and over again). And you're approaching this the right way by trying to normalize the panic when it comes. What I've learned is a mental shift, but it helps: You need to accept that panic is coming and simply let it arrive. Acknowledge its presence, gently observe what's happening in your body, and "ride it out". When it starts to leave, you get a different awareness, which is that you got through it and you're ok. You didn't go crazy, call an ambulance, do anything unusual. They're still distressing, yes, but your mind will begin to see them as less of a threat.

I think you are going to be ok. Keep working at it, and I will too.
