Anexity problem. bad.?

i have terrible terriable anexity. its really starting to affect my life. i can literally be doing the most random stuff and i can feel my heartbeat start racing. also i cannot sleep do to it. i will be laying down and start thinking, and next thing i know my heart will start racing a so so so fast and i will lay down for hours at a time. its really starting to affect my life. taking drugs like xanax is out of the question for me do to my former drug addicting(clean for 9 months) so my question is, are there any non narcotic supplements i can take to help get rid of my anexity?
