I never thought I'd start complaining about "the voices"...How many of you have friends with mental disorder?

That's scarily similar to a friend of mine, she's happy one minute, down the next, talks too fast etc. She generally seems to tell her friends just about everything, and we accept her for it, no one's perfect and we all have our flaws. If you feel you can trust your friends enough with it, tell them. They'll appreciate that you trust them enough to do so.
