I don't even have many friends, but I like DEEP relationships, so I tell all my friends about it early on. If they don't like it, then they can't deal with me as a friend anyway, so **** them. I even ordered two funny bipolar t-shirts this week. I don't hide it at all. I am a wild, intense person, with intense relationships, and bipolar mania is a defining part of my personality. I am a proud "OUT" nutcase.
