Medication won't fix the problem. It may help, but you may also become addicted to that as well. For supplements, might I recommend St. John's Wart or 5-HTP. Both are inexpensive, and both are natural. St. John's Wart is an herb that helps with mood health and 5-HTP is a precursor to serotonin. If you have the money, Onnit's New Mood is a great supplement. I took it after my father died, and it helped to keep me calm when I was going through all of the grief.
Ultimately, you have the answers within yourself. Anxiety is often psychosomatic, and taking a few deep breaths and simplifying your thoughts is far more effective than taking a highly addictive pill ever will be. To be blunt, you need to start taking some notes and figuring out how to solve your problem rather than dwelling on the fact that you have anxiety. You just said that you were unemployed. Well, did you have this kind of anxiety when you were employed? You also said that rapping calms you down. Have you always turned to PMO every time you felt anxious?
