chest pain

i am having like serious chest pain and abdominal cramps and i feel like i can't breathe and i am o so very tired but when i try and lay down to rest sleep totally escapes me. whats going on man? i'm no more stressed and pressured than usual. I'm kinda freaked out. (ok, and i have this persistant cough, and i can't get it to stop and when i cough i taste blood-so that contributes to the whole freaking out thing as well)
