Meditation helps compartmentalizing your thoughts, so if you meditate, you might still notice the problems and be angry at them, but you might be able to better control the anger and tame it.

Also, it sounds like you may be angered by something else, so you are on edge, and it’s easier to be angered at a door than at someone or at some situation. Going to a shrink may help disentangle the anger.

And yeah I am with you: fuck google maps.
