I was doing good with panic attacks, decided to smoke a bit of pot after 2 yrs of not. panic has come back, now 3 days and i can't shake it.

Panic exacerbated by: pot is not at all uncommon. While some people find marihuana relaxing, others, and particularly those who tend to be anxious, often find that marijuana actually causes them a great deal of anxiety. I would ring your doc straight away, and let him know how you're feeling and the circumstances that seemed to provoke your exacerbation. If you're completely honest w h, he'll be able to help u best!
