Yep, I sure do. I know I did nothing whatever to cause this dysfunction of my brain, and currently the jargon available to our age is 'mentally ill' therefore, I am.

Someday they'll call what I have by it's right name - a chemical imbalance; however, that requires some serious teaching of the masses. Until that time, I'm fine being 'mentally ill' and explaining how my particular bipolarity works and what it causes in my particular personality.

Thus proving there is no "one size fits all" when it comes to being 'mentally ill'. Sneaky way to teach people, innit?
