Many health issues. Help me with it.

Hey doctor! Im 22 and I've been facing alot of issues with myself. Starting i used to have severe headache problems. I still have it but its too often now. I used to take saridon probably everyday to deal with the headaches. Pain in calves when i run even for a minute. I feel tired all the time. I suffered pain in my testicles few times. Sometimes i also have a very severe cramp in the centre of my chest where the rib cage starts to separate. It is usually when i exercise. And i faced sex problems as well. Not lasting for even a minute. im stressed, depressed and might be a victim of anxiety. I feel i have many symptoms of low testosterone. I haven't shared it with anyone yet. And yes, I started smoking up 4,5 years ago and have also consumed cannabis/marijuana from past 2,3 years. I have gained fat now and also i have man boobs which might be because of the mass gainer i had while gyming an year back. Help me with it. Thankyou so much. I'll be waiting for your revert.
