Will I ever be able to exercise again?

[Evil Sam]

Hi, I am a healthy 23 year old male that is suffering with PVC's (Post Ventricular something...) or in other words my heart skips a beat. I tend to get these skipped heart beats when I get really angry or anxious. I have been dealing with this problem for about 3 months already and I have changed my lifestyle complety in search of a cure. I have stopped exercising as much because when I am done with doing exercise my heart skips a lot. I have also stopped drinking alcohol, and caffeine since they are the cause of heart skips. I have asthma so I don't know if that has to do with anything and I used to be an alcoholic and I have gone clean for about 1 year up until this summer when I drank with a couple of friends and then this all started. I don't know if its because of the alcohol, stress, caffeine, or some heart disease (my Blood pressure is 120/80). It really doesn't make sense at all as to why the heart skips are happening to me since I am a healthy 164 lb, 5'8, 23 year old. I used to love running and being active before this all started, but I fear that if I push myself to hard I am going to pass out or just flop over dead...and please don't tell me that I need to see a doctor as an answer..I want to know if anyone else has had this same problem...
