I suppose you are not on meds or in treatment? I actually have a lot of panic attacks, fear, anxiety and depression. I'm on meds and I have my first therapyst appointment on July 18th.
I spent a lot of time alone at home and I have a lot of issues that makes my mind explode. The only thing that makes my mind be a little calm is reading.
It makes me go out of reality.
I also try some mp3 guided meditation.
I know how difficult is try to stop fears.
