I feel that too man, it's like you don't allow yourself to just chill

It seems as though my body does not know how too

Swimming or music (playing or listening)

@Captainjackass exactly you need to chill a little more step back a bit and top stressing as that is not good for you

A funny movie, a book, and getting outside to the woods or the water

Relax ? What's that ?

Nature. Preferably the wilderness and from a place of humility. Puts you in the moment and you come out the other side better. Lot of studies are proving that.

Going for a massage or a float

Lay around and chill.
