Join the club! Today I am having a near full blown panic/anxiety attack! Our fears are not quite unfounded....like you w/ the medicine, I am having major surgery tomorrow and I am ramping up the same way you are doing!! I am shaking and having tachycardia....trying to breathe normally.....etc.
I just wanted to say that I understand. It's very hard to keep those negative thoughts from circling your brain. I hope you get over that soon.......and I will also try!....OOOHHHHMMMMMMMMM...meditation! Anxiety plus ADHD (me!) really sux!!!
Shalom, Hannah
