I nowadays takedeepbreath. I need to do?

I nowadays take deepbreath. If I talk a lot I need to take deep breath. If I walk I need to take deep breath. I have checked TMT last year. It was fine. I am healthy except for Asthma which I get slight chest tightening at times. I had high BP with ulcer but not now. I still have Nebistar 2.5 mg given by Cardiac specialist on alternative days. I am obese. I do 1.5 km brisk walk on alternative days but do need deep breath. My penis erection is not that rigid or long lasting. I am not married and not in a job. I feel like commiting suicide at times as I lost my youth nearing 40. No job, and no marriage. I suspect my artery may be blocked. Please advise what I need to do? My mother is supporting me financially, instead of me supporting her. I feel guilty but I am helpless. I gave up my BPO jobs in past. I did not like it, as no respect given by my colleagues. Before jobs I did business failed. I hate my cursed life.
