Thanks for choosing health care magic for posting your query.
From the description that you given it appears that you are having a type of anxiety
disorder. But still many question are yet to be answered before we label it as anxiety disorder.
Moreover even depression
also needs to be ruled out.
Start doing exercises and also take a proper diet.
Consult a nearby psychiatrist
who would like to talk to you in great details to identify your problem exactly.
Hope I have answered your query.
