I am bipolar. I have bipolar. When "outing" myself to people, I've always vacillated between these two sentences. But I think I've finally settled on the former. "I have bipolar" sounds like "I have tapeworms", and after 14 years of symptoms, I'm ready to say that my relationship with my disease/illness/condition/insert-word-of-your-choice-here is symbiotic rather than parasitical.
