I will admit that, for many years, I had zero understanding of what bi-polar disorder is.
If I am being completely honest here, I will say that, when I was younger, I basically viewed it as a personality flaw/weakness.
Over the years, I have become more sensitized to it, but I didn't really understand it until my coffee companion from this morning, Charles Blackwell, explained it to me as succinctly as anyone ever has.
It's the difference between feeling down and worthless and KNOWING you are worthless.
The difference between feeling invincible and KNOWING you are invincible.
Read his fantastic post

It will, hopefully, shed some light on it for you. I know it did for me and I am grateful to Charles for his openness.
