I have suffered from really bad panic attacks this past year, I'm taking medication now, but what also works is breathing slowly or what I really like to do is watch a funny movie or TV show, Arrested Development calms me right down! :)

When I look up in the sky I don't see any magical floating bastard that rules over us, so there is no god, thankfully.

I get that a lot and I have messed up knees so that might have something to do with what's going on with you.
