If anybody could help, that'd be great. I'm a 16 year old male, it's the middle of football season so I exercise daily, but when I try to sleep - from once a month to a week a month - I have trouble breathing. I feel tingling all over my body, and I'm afraid to go back to sleep. I feel my pulse and it freaks me out because it seems unsteady. It'll be hard, then softer; normal paced, then speed up. It happened at about 11 PM today and now it's 2:30 AM and I have yet to fall asleep. I tried to relax, I laid down and watched TV and took a shower and tried to sleep again but nothing will work. I feel light headed, I've been burping, and I had diarrhea at about 1:40. Also the inside of my forearm is sore from a nap earlier in the day when I fell asleep on it. I'm just freaking out and have no idea what's going on. I'm sick of it happening because it's been going on for a few months now. The pulse thing especially freaks me out because it makes me feel like I'm going to die. I really am confused. Please help. Thanks.
