hi i am 23 and for some time now i have been having severe moods, sometimes for weeks on end i become extremely down and find myself lethargic and not wanted to do anything, and then it for no apparent reason goes to the opposite extreme where im chaotic and believe i can do anything.  these mood patterns are starting to affect my life in bad ways though and would just like some advice
