Hi there, welcome to PC,
I just took a quick look at your post (I need to be somewhere soon) but I just wanted to say that "rage issues" are NOT limited, nor should be only associated with Bipolar disorder.
While "anger,rage and/or violence" can occur when a person is having a manic episode, such feelings/actions can stem from many other disorders, physical and/or mental.
It is most important you rule out physical and also be professionally evaluated by a psychiatrist, to ensure proper DX(s) and treatment plan(s).
There are many options,alternatives,including talk therapy,etc. that can help get you on the road of stability.
Please keep the faith, what seems impossible can become "the possible" with time,effort and patience.
I'm wishing you lots of luck and innerpeace with this all.
