Confused about the former replies, the young man is just looking for some help, not the rule book.
Addressing your post, I uniquely enough have had similar reactions to more potent strains of bud, and currently must be extremely careful when smoking at all. Long story short my mental health was compromised (I believe) by smoking extremely strong bud too frequently. After taking a 7 month break, I took one hit and relapsed. My best advice from personal experience on the subject: If you cannot see yourself quitting weed (which would not be a bad idea if you do not medically need it), take a short break and smoke some lower grade bud and see what happens. If out of a pipe, take a small hit like you would a cig, and don't hold it in. If you are O.K. after that, tread lightly and stay away from potent buds. Currently I must drink before hand, or I will most likely panic.
Hope that helped.
