I get along with ElsaMars, it's about the right person. In addition to that, personally, I don't like the idea of me telling my new friends that I have bipolar when I am not in a good condition, no matter how close I feel connected with them. So at first few months I'd show them that I am a good friend, that I am not a mean person, that I am not judgemental about them, and that I have an open-minded mind about their issues. I'd give the best version of myself to them. Doesn't mean that I would lie, it just means that I won't go into details. When the time is right, like let's say, there is a conversation about mental health, then that would be the time I tell them. By telling them when my mood is under control, I'd be able to give them a good explanation, therefore the possibility for them to understand is higher. I know there is no guarantee that they will understand (or still be friends with me) after they know the fact, but by being a good friend at first, when they are judgemental about me, I can say "I never judge you, so why do you judge me?", "You think I am a good friend few minutes ago, I had bipolar few minutes ago just like now, what's the difference?". If in the end, after I've done my best, they still cannot accept me.. then shame on them! I don't need ignorant as my friends and they can't bring me down.
