Hi Max, I can relate to so many things you have been going through. The painfully long time it takes to recover from a panic attack, feeling lost and confused while driving, not understanding what triggers random panic attacks, having your day derailed..
I'm so sorry to hear about your other health problems. I can't comment on those things, but I hope you have experienced medical professionals, who were able to exclude other illnesses as the source of your physical problems.
It's very admirable that you are trying your best every day, even when it's enormously difficult to cope. Isolating will make matters worse long-term.
I hope your therapist is helpful. It might take a while until you find out which techniques (and/or meds) work for you. Meanwhile it might already help a little bit to communicate with others, either via pc or in real life through friends, group therapy etc. I wish you all the best
