I think my brother has some mental health issues

I definitely think my mother and brother have mental illnesses.

My brother LayZ boy has admitted that he has OCD (obsessive-compulsive disorder), although he will deny it vehemently if you question him about it another time. He's very weird in that way. He'll tell you the truth about something in a very small window of opportunity for the truth that he opens up every so often, but if you ask him about it later, he'll slam you and tell you that you are sick in the head for suggesting such a thing! As if he never said such a thing to you in the first place. I am not sure what that is about, but it sure is not normal behaviour.

LayZ boy is also very manic. He often gets all excited and starts doing all these manic things, like running up and down the hallway, banging on the walls, talking to himself (very loudly), talking to the cat (also very loudly) and very obnoxiously. During this manic phase, he starts talking fast, loudly and incoherently. In addition, there are so many times when he does all sorts of things around here, starts measuring for his "home stereo" locale and talks very loudly and rather incoherently to me about things that make no sense whatsoever, answering questions I have never even asked him and then telling me what a fool I am because I don't know of his plans. Yeah, sure, LayZ boy, you are not sick in the head!

Then LayZ boy has his down times, where he functions very slowly and acts like a sloth. He just sits in his bedroom and watches DVDs all day without eating properly or doing anything else but smoke his cigarettes and behaves like he is very depressed.

I am beginning to think LayZ boy has bipolar disorder, which is very consistent with the up and down and very inconsistent and extremely exaggerated ways he behaves.

LayZ boy also has very big problems with his anger - he has no impulse control, he gets angry very quickly and cant control it. I think that's because he has no ability to use rational and logical thinking - all of his thinking is very exaggerated and irrational, based probably on fear.

Then LayZ boy takes sleeping pills almost every night, to lull him into an artificial slumber and as these medications are very addictive and can produce depression and anger symptoms, then no wonder he behaves the way he does. Additionally, LayZ boy takes a very strong opioid medication (Oxycontin) which is akin to heroin for his "pain" and as that medication is addiction-causing and can cause depression, anger and a whole host of other negative emotions (due to the way it works on the neurotransmitters), no wonder LayZ behaves the way he does.  These medications just make worse the worst of his personality and cause his mental illness issues to get much much worse.

I used to always think my mother must have dropped him on his head really hard when he was a child and that is why he behaved the way he did. She probably did. Neither my mother nor LayZ boy will admit he has huge problems.
