Hey there. I've had A/P for eight years as well. I'm in your same boat too, as I learned to control my panic and thought I got over it until a few months ago when it started getting bad again. (due to a traumatic experience)
I was having panic attacks every day (sometimes twice a day) and I was miserable, but wasn't on meds, so I got on lexepro and ativan.
Fear was starting to rule me again, I couldn't even go to the doc without someone. I did make it to the doctor by myself however, a week ago which was good.
But with A/P I can't handle a lot of stress either, and it sets me off as well. I would suggest just relaxing and trying to clear your mind, maybe draw/paint and listen to music at the same time?
Tell yourself "you can get through this" and "things will get better". Maybe you need to switch meds? How long have you been on them? I would definately consult your doc about that. Maybe you just need a different med.
I'm seriously taking baby steps with everything. My sister has A/P and has had it for 12 years, and she was asking how we should get better, wanting to make a whole list of things to accomplish. I just don't work that way though, it's one thing at a time. "Let's try to go to a mall" and THEN go from there to see what I can handle, yanno? Thinking about doing too many things at once sets me into panic mode, so I just look at the one goal, and focus on that, and try to see if I can accomplish it.
And yes, I've spent days in bed or on the couch not even caring what was going on in the world, not even moving, just drained, and anxious at the same time.
I'm sure others will be able to help you more. I thought I'd just try to help. :)
