Hi, I've Been Experiencing Heart Flutters, Like Sometimes My Heart

Hi, I've been experiencing heart flutters, like sometimes my heart skips beats. Sometimes it beats rapidly. Sometimes I feel like anxiety in the worst way. Sometimes my hands shake. If I do any kind of physical activity I can only go for so long before becoming fatigued. I am 21 years old. I first noticed all of these effects as a result of me taking a fat burner I was an athlete and I just became obsessed with my results from working out that I wanted my body to look even better. The product I took had ephedra in it. I was taking the fat burner since I was 19, once again I am now 21 years old. And you know sometimes I just feel like I'm dying. When I was 20 years old I had an episode where I had passed out in an outside setting I must admit I was working out really hard that day and had not hydrated properly and was over dressed in the sun working out so as a result I was running a pick up game of basketball and I walked off the court because I felt a dizzy. And I honestly didn't even know that I walked off of the court every one told me after the fact. So I walked of te court to try to sit down I knew I was trying to sit down because my body felt like just giving up like I had no control so I couldn't make it to the bench to sit down so I ended up going head first into the bench passing out for a few less than a minute and some say that they saw my body shaking which I would assume to be sight of a seizure. I never went to the hospital. Foolish of me yes I thought I was just probably dehydrated and at worst from falling and such a hard head blow a concusion would come of it. And so I went home didn't fall asleep because I know you can go into acoma so I just stayed up and ice my head. Rest for about 2 weeks or so. And I never felt that feeling again till about a 5 months later after I came homebfrom fall semester in college. I was a full time student and athlete and at most I just slept a lot. And during practice I get fatigued quickly. But I'd still put in more work after practice and training etc and I felt great actually. So after the semester I came back home for my brothers wedding in November of 2014 mind you my first episode was in August of 2014 (Park Incident). And during my brothers wedding I felt alright every one said I seemed to look sick. I had maybe a sip, literally a sip of liquor just for the occasion I do t even drink at all. A sip that night. The next morning I woke up and I just felt very hot. I went to use the bathroom to pee, and suddenly my heart started beating fast rapidly and then it took 3 of the slowest beats ever. I honestly thought I died. And that's all I remember was waking up, stuff all out mom next to me trying to wake me up and brother slapping me trying to bring back to life. Scary moment indeed. So my whole family was at the house cousins and all because of the wedding. So then the ambulance and for department showed up. I could see everything that was going on but for some reason I was not able to speak. A fireman told me I was experimenting syncopee or something like that. So We get to the hospital. They do every type of test on me. Blood test, brain test a bunch of stuff. Sonogram. And at the end of the day they did not find anything. They just said my heart looked to be dehydrated. They wanted me to follow up and take this heart monitor with me but I ended up leaving back to school about a month later because I was feeling better. And I got through the semester even worked out harder than. Did before just became fatigued faster than normal. A year or two later 2014-2015 and now 2016 I feel as if I have gotten better but worse. Better in a mental aspect because before I had really no or pen just dying like that's how bad I was feeling couldn't sleep on top of already not being able to sleep just as a child. Anxiety, rapid heartbeat, heart palpitations, flutters skips beats etc quick fatigue. Just over all hell. Now tool this day now right now I just feel like I am not sure what's going to happen next. Sometimes I feel ok great in fact after I woke out but not during the workout. And sometimes I feel like dying because the pain is a nusince and it's tedious and I just want it to go away and I want to live my life I'm 21 I've been very mature all my life and yet now I feel like this is making me even more humble than I already am. I don't have many friends anymore I don't associate with a lot of people, I don't party drink or smoke. I read I'm focused on my goals I just recent my gave up all athletic aspirations after years of this pain it was finally time to let go of the things I worked so hard for physically and from an athletic standpoint and I honestly don't know where I go from here. I just want to be alright I want to be FBI one day or a lawyer, forensic scientist. I don't want my heart to hold me back from chasing my dreams and I haven't let it as of yet except for athletics. I've tried to diagnose myself many times and closest thing I got was Afib. Even now my chest the center of it feels like a pulled muscle or something i don't even know it just hurts when I run for to long tightens up and is a sharp constant and consistent pain in my chest and around my heart sometimes it almost feels electric like it's shocking me. I honestly don't know. Some one save me from myself please! Thank you!
