I am a little ****her along in this gym thing than some of you. I was a mess about a year or two ago, but slowly and surely started crawling out. No I did not use anti-depressants, I did however use valium. Anyways, about the gym... I paniced daily and horribly after just going bonkers being too stressed out over my custody battle and marriage issues. Anyways, I stopped going to the gym as I become frightened of my racing/pounding heart beats. I finally, thru various books and programs like this one, learned to STOP being afraid of racing heart rates. I can now pump iron again in the gym. This biggest obstacle for me was the first few times and first few lifts, even to this day. I DO NOT however let it stand in my way, and THIS is the way I have used to get this far, I now go to the gym daily. Most of the time by myself and sometimes with my wife, but I go regularly and pump out good hard weights. I just keep in mind that I have been doing this for 15 years and there is NOTHING wrong with me, it is simply panic/anxiety issues, and that is it! Sure enough, I go to the gym, pump iron and voila' I'm still standing and feeling fine.

Just try to remember, you are going to be fine! I used to pack a cell phone in the gym and find a quiet corner and go at it figuring if I had a heart attack, I would just call 911 and be picked up. This never happened. I would raise my heart rate and it would go VERY high with my worry along with it, but you know what, no matter how bad I felt and how terrible my heart raced and pounded, a year and a half later, I'm still standing with no heart attacks hehe.. I even forced my d
