Your post was r-e-a-l-l-y helpful. I am trying to adjust to my situation. I didn't realize I was bipolar until this year because my highs didn't seem very high. But I think I understand what you are saying about the introvert-extravert thing. If I have to put on the happy face and be the extravert, it is exhausting and I need time to recover. But because I am able to do it well (for now)- others don't understand the strain it brings to force myself to be up when I don't feel it. I seem able to get in gear most of the time like you said because a mildly manic phase seems to kick in and get me through it.
Thanks.
