chest-pain and breath - difficulties.

I have recently been experiencing alot of things that I think might be symptoms of turning into a lightbody, although I am not sure, like digestive problems and feeling inceadible tired, also had feelings of bliss one day, and then things are dark the next day. but I am a bit more scared by the pain I often feel in my chest, possibly in my heart. also, every day, I have difficulties with my breathing. its hard to breath inwards, like there is not enough air. my doctor didnt know what this could be, and for some reason I havent been going there again. could this be some of the symptoms? and also, I am feeling an increadible attraction to the sun:) I am somehow needing it like never before.
