I've suffered from anxiety my entire life. To me, its worse than depression.
My hands will literally shake like a leaf when I'm really triggered.
I used to take Ativan for anxiety but coming off it was horrible. Now I just take an SSRI.
One thing I've experimented with is EFT. Tapping. It seems so hoaky to me but I've tried it and had some success. It doesn't always work when I'm really spun up but it's easy to do and provides some relief.
Of course working out until you are exhausted helps too. But my anxiety has held me back from going to the gym because I can also get dizzy. I would hate to wake up on the floor in the gym surrounded by people fanning me with their workout towels.
