How open are you guys when you meet someone? Do/did you tell him or her when you first meet, or do/did you wait? Do you find that people get turned off by it (my biggest fear)?

I ask because, first, I have gone on dates and we will get talking about our lives. A lot of stuff I have done (education-wise) was a result of my anxiety, but I always hesitate to tell a guy that because I'm scared he'll be turned off by me because of it. But how long I wait to tell and should I tell?

On the other hand, I know people who will tell a potential friend or significant other right off the bat that they have bipolar/depression/OCD. I have just heard acquaintances do this, but I don't know how that relationship went for them (ie. did the person "disappear" or did they not care).

I have never told a potential friend or significant other. What about you guys?
