Could it be that schizophrenia and bipolar disorder has been misdiagnosed for someone experiencing the extreme "down" from the euphoric "high" from extended drug use for decades? I am just guessing but if someone is on drugs for more than half of time they are awake, over time wouldn't the body and mind consider it normal? I have seen a few friends and co-workers go through the "bugs under the skin" episodes. Then the next time I see them, usually the next day, they have fresh scabs all over their face and arms. These fools pick at these imaginary spots believing to remove these "bugs". I hate to admit but it is hilarious, to see someone subject themselves to doing these sort of things. Sorry about thread jacking. I just can't stand when people place blame on others/things, when the problem/blame falls on themselves to begin with. Seems like in today's society, there is no such thing as common sense. Instead, people seeking pity is much more common occurrence.
