Tried. Broke my composite handled woodcutting axe, and slashed a giant hole in my shed with a brush axe.

I'm a person with severe anxiety issues, but what I find best is to be busy with something. Standing idle or doing little makes the anxiety worse to deal with for me, so I recommend doing anything to keep your mind busy, from reading a book to watching a video to playing a game.
