I drank strong coffee prior to smoking weed..I need help now, Please!?

I forgot that i drank the coffee earlier that night, so when it came time to smoke with my buddy it skipped my mind. I was cool for the first 30 minutes we were playing a game and, me being how i was got an adrenaline rush from playing Nazi Zombie. So after a few round of playing i noticed my heart started to pound really fast. And i couldn't link to why it was doing that, i just thought it was the adrenaline pumping. And i am not a first time smoker so that wasn't it either. i told my friend that i had to chill for a minute because i then started to freak out. So i lay down for a little, then got up, then lay down again, walk around and so on. It lasted for about 2 1/2 hours before i started to come down, but the whole time i thought i was going to have a heart attack it was pumping so fast. And while this was happening my body was obnoxiously shaking. My hands and chest were the worst. and while i was still under the influence everytime i closed my eyes, i woke up catching myself not breathing. Either i forgot to or something else was happening. So now 5 days later my chest hurts and my heart feels like it is aching, and every so often i get pains on both sides of my chest. Could it be that my heart is sore from a night of non stop pumping. Or my lungs were deprived of oxygen due to me not breathing properly. I don't have medical insurance so that is out of the question, and i know that chest pains usually isn't a good sigh. Ever since that night i have been waking up in the morning with minor chest pain but it is somewhat persistent. I am 22 years old male, I don't get a lot of exercise too. So please anyone I'm a bit nervous and i need to know if there is an alternative to what i can do. I have been taking proper breaths as well to help massage my insides. please help thank you
