23 Years Old Male, I Lived For Like 3 To

23 years old male, i lived for like 3 to 4 years of constant stress(emotional), it caused alot of problems to my health, like washing away of muscles, joints, neck and chest pains, numbness in the face and others. I feel like i'm a 60yrs old person, i am not stresed now but the effect from that stress is giving me problem. If i feel sad for something happend, within just 2 seconds i will start having headache, chest or joints pain. I am thinking if i have adrenalin prblms. My question is can all these effects be reversed and what is the solution.
Thank you
