Facebook taught me a lot about who my friends are. I had the typical account with a lot of people I haven't seen since high school and I kept quiet about the bipolar on there although some people knew. That turned into 2 people being very nasty to me after I caught them making fun of me and I left the account and went to another that is some former co-workers, my family and extended family, a few old friends and that's it. I'm open about bipolar although not usually about what specifically is going on at any given time, just more I'll post about public policy and how it affects me or the like sometimes. I like it much better this way. I wish I hadn't learned the hard way.
