I'm so angry at everyone every day! What can I do?

See a Mental Health. Professional for evaluation , before getting u self in trouble.
Develop a plan. 1. forgive. its not something that allows bad behavior, its something you give yourself so you aren't angry all day 2. start your day with an intention. it could be "today i will not argue with anyone" then let it simmer in your unconsciousness. 3. have an anger plan of what you will do if you get irritated - breath, listen to music, call friend whatever you want just so you have an alternative.
