Suggest Treatment For Chest Pain, Anxiety And Shortness Of Breath

I have flat out been feeling like crap. I have been to 2 cardiologist in last year and my regular Dr and a lung Dr. and they are not finding heart issues but my chest just aches. My cholesterol is a little high and my lipids are too. When I have drank alcohol I had a three day hangover where I literally could not get out of bed. I am always tired. I have had 2 CTs of chest, noting really showed except for little bit of fat in the liver area. Stomach test showing a little bit of reflux but honestly until they did test never had any kind of symptoms of it. I have a ache in my back on right side not at shoulder blade but about 4 inches below arm pit that really doesn t go away. Anxiety all the time and I am always tired. Shortness of breath with very little exertion. I have gained weight because even walking for short period I am out of breathe. Cardiologist wants to do sleep study because I snore??? The shortness of breath has been going on now for over 2 years. I don t have good insurance and just keeping going more in debt with test after test. I am not sure where to go next? researching I have had things like Lyme Disease come up but never tested? I m at a loss of where to go next? Blood test for auto immune negative. Mom does have Lupus and Dad M.S. but don t seem to have any of those symptoms. Any questions for me cause I m sure I have other things that I m leaving out?
