Chest pain feeling uneasy. Take by me?

I hv done some test 2d echo, ECG, TMT stress test. All test are normal. Colestorel is 158 BP also normal 120/80. Calcium and Alkaline phosphatase are also under limits. CBC total blood count, sugar, urine test all are good. Doc told me nothing happened with u. But still I m feeling chest pain, back pain exact opposite of heart and pain in ribs. After dinner feeling very uneasy. My office timing is evening 5 pm to night 3 am. When I tried to sleep in night I m feeling very stress and uneasy. In 2d echo test hearts compatibility is 64% and blood circulations are normal. I already quite smoking since last 8 months. I take two times tabaco in a day. I m trying to quite tabaco. Now i m doing few exercise on regular basis. It might be some phycologist effect bcoz we lost one of our colic in my office. Could you please advise to me is there any chance to hearth stroke in this case ? And what precautions will be take by me ? Appreciate your help...!!!
