Do I have heart disease?

I'm 6'2 200 pounds, 19 years of age, I'm not in great shape, but I'm not overweight quite yet. I have a good bit of muscle tone to add to that... But to the story... I have been having problems for 2 years with my heart. Back in 2013 a couple of friends and I partook in some illegal activities, and I smoked pot and drank about 3 red bulls, which sent me into an svt attack... I went to the hospital, they said I was fine. Over the course of these two years I have had "angina" "water retention" (feet swelling) everything that comes with chf and so forth... But I have had countless ekgs and blood tests done... And a few chest X-rays. They all say I'm fine! I just have a severe panic and anxiety disorder... My Bp has been up to 185/105 and pulse will just spike up really high out of nowhere... I've been to several doctors and they all say I'm healthy as an ox... I just need to "see a psychiatrist" but I can't help but to feel like it's something way more serious... (Tumor, chf, cardiovascular disease etc) it's killing me. I just want to know what's wrong with me or I want my normal life back...
