Help asap!Possible anxiety disorder, lung issues or muscle tear!

Hi, i've been having some trouble lately and it seems to deal with my chest and lungs.A while ago I started get pains in the left side of my chest and it quickly got worse.I thought it might've been a muscle pull and my doctor thought so too and he prescribed something for me.It felt okay for a couple days and then I started having breathing trouble and had tickling in my chest and it felt like I was breathing through a straw.One night it got to the point where I could hardly breathe at all, my heart was racing and my chest was burning.I went to the hospital and they described it as an anxiety attack.Things were good for a week or so until I went to a football game.I stood up to cheer and I wasn't even shouting for 2 seconds and I felt like my lungs exploded, I couldn't breathe for a few seconds and my abdomen and lungs felt like they were on fire.After a while it subsided and I was back to feeling great again.But the next day while I was taking a bath, the burning in the lungs abdomen and now the lower throat came back as well as the feeling that any breathe could be my last.This happened again just recently and I really want to get to the bottom of this as it worries me alot.It sometimes costs me sleep and I can no longer participate in sporting activities for fear of more symptoms like this.I'd like to know where I go from here to get this fixed.Thanks!

I should also add in that I do NOT deal with stress and anxiety well at all.I had a very stressful couple years 6 or 7 years ago (probably my most scarring memories) and a VERY rough year with the passing of my beloved grandmother on my birthday and my girlfriend whom I loved alot breaking up with me.Both of those events had a big effect on me and now for whatever reason i'm getting anxiety attacks and EVERYTHING get's to me.ESPECIALLY fear of health right now.The hospital gave me a breathing excercise and highly recommended that I should see a therapist but i'd like to know hands down what's going on before I do anything.I should also add that I had two xrays in my hospital and doctor visit (ribs and lungs) and everything was fine.My vitals were all normal although my pulse was a tiny bit high at 81.

Here's what happens in what I believe to be my newest attacks.My abdomen starts burning and getting tight.My lungs start burning, my throat seems to get warm, I start to sweat, I start having breathing trouble and then I panic and start looking for explanations on health websites which doesn't help the fear factor at all.
