don't deal with anger by trying to "let it all out" and expressing it. it will just stay longer and create more. release the anger by letting go of it. take a step back and realize its futility and the harm that it is causing you. it feels bad and it is bad. release it and let it go. deeeeep breathe. and agaaaiiin.

you'll get angry at times but don't stay angry. you'll get over it eventually right? well just decide to save yourself the pain and get over it immediately.
