Does any else live with a variation of week to week or day to day behaviour going from completely:
"I want to hug the birds and the bees and spark up honest conversation with everyone and blast the world with my sunshine personality"
to
"I must stay away from society because all I do is bother people and I just need to sit in my corner, be quiet and go home without bothering anyone"
?
At the same time you know you're not bipolar since when you do talk to people you don't have wild emotional variations going from anger to joy in the space of seconds.
