I feel like im going mad

there is this unstable feeling inside me, I feel like im going to burst, I can never relax, I always have to be doing something. I used to have no worries, and felt good all the time. Now, just millions of things go through my head, I can never just sit down and feel relaxed. What is happening to me?

breathing exercises. use them.

Jerk off ^^

You have an erection, sir.
