Is There Something Wrong With Me?

For the past year or so i've been having this acute sharp pain in my chest once in a while. I have difficulty breathing at night and sometimes wake up with shortness of breath. I can't take deep breaths anymore. Sometimes sharp back pain. This past month though i've been having a stomach ache for almost everyday. It never seems to be like I ate bad food or anything but it's a pain and I feel it. Today I woke up and I felt this new pain on the sides of my bladder. I've had it all day. It feels like that feeling after a guy gets kicked between the legs.. It hurts. It mixes with my new stomach and my old chest pain and a annoying random back pain. What is going on with me? I might be dying...

please note I do have heart disease (tricuspid atresia) I am also now overweight and I was never overweight in the past. 5'8 200lbs


i am a 20 year old male.
