Congrats on how far you've come!
My anxiety has disappeared since quitting alcohol.
I'd have thought pot would cause anxiety since its known to cause paranoia which is (I thought) a form of anxiety. (I'm not second guessing an Rx just making a casual observation)
I agree with Juppe - but I think working out is the answer to almost everything :-)
Until you find another suitable job, as Dee said, volunteering would be a good time filler.
