Is there an activity that calms you?

Yes, walking alone in nature.
It doesn't matter what state i am in when i start, i could be furious, angry and upset, or just extremely stressed, the moment i start walking it all clears up.

The thoughts are all still there, but i am calm and am able to understand these thoughts and come to better conclusions.

The negative feelings just go away and i am left with a sort of peace i feel only while i am alone in nature.
