Jess,
When I was going through my separation I had panic attacks while I was driving and would have to pull over. I thought I was losing my mind for a bit there. Thank my HP for good anti-depressant/anti-anxiety meds which to this day help keep me feeling sane.
I've tried the Xanax too, and found it made me tired and feel out of my head - like "balloon head". Fear of the unknown for me was a major trigger. But as I started to put more trust in my HP the attacks came less frequently. Now its more my mild case of depression that I have to manage.
It got better for me as I learned more tools to help myself. A few deep breaths and a mantra of positive affirmations might help.
Sending good ju-ju your way darling.
Petunia
