I need help. im getting angry and disrespecting people and then i don't remember it or don't realise i do it and that isnt like me at all. please help.

Irritability : Many people that suffer depression may have irritability and act in ways that they feel they cannot have control over. However, if you feel you are having significant anger issues, extreme behavior fluctuations( swings), or can't recall things you have done my advise is to get a psychologist consult so you get a formal evaluation. It will be very helpful so you understand it in more depth.
