It's ignorant, glaringly malignantly painfully ignorant. I know, I know, "it's just a T-shirt", but it's the shirt combined with the copy that is the tragedy here.
You'll never have to make up your mind in this super soft black shirt that says in white chalk print, "I'm bipolar. Are you? I'm not."
Being bipolar is not the same as not being able to make up your mind. It's not a fucking choice, because if it was, NO ONE WOULD EVER CHOOSE TO TAKE LITHIUM. Seriously, lithium is a fucking POISON. It does seriously bad shit to your brain and your body if you're not careful.
I recently had the absolutely terrifying experience of watching someone I love dearly, who is, yes, bipolar, deal with a quasi-overdose of lithium. They had accidentally gotten dehydrated and, as a result, their lithium levels went right over the line from 'theraputic' to 'deadly'. Fortunately (and this is why I tend to believe in God more often than not) not only was I there by my mother too, and if there's anyone I want around in a crisis it's her. We didn't have to go to the hospital, but it was a near thing.
You don't get a choice, being bipolar. When your brain chemistry goes one way, you're up and on and ready to tackle anything that's thrown at you until it slides back the other way. And when it slides, it doesn't just stop at the middle, it goes right over the fucking edge of the cliff and you're ready to throw yourself out of a moving vehicle in order to kill yourself. That's where the name comes from, as did the old classification -- if you were Manic-Depressive, you're now bipolar.
Like I said, maybe I'm oversensitive, but this is just so blindingly ignorant that it's almost breathtaking.
