There is a Social Group for 55 and Over
http://forums.psychcentral.com/group.php?groupid=157. I know it's an active group and I think has a couple dozen members, so
maybe there'd be a bipolar female ... fairly good odds.
There're so many bipolars here and many of us older women, I think if you're patient and keep reading, wait for the holidays to get over, you'll find some good matches.
Normally I'd be happy to have you over to my place--I'm a 66-yr old bipolar alcoholic--but I'm sorting through a bunch of physical problems right now and have a situational depression digging the ground from under me as fast as it can. I'm barely keeping myself out of the hole, so I'm not much use to anyone else right now.
The holidays have taken a pretty big bite out of everyone's reserves, energy, and time--so let everyone catch their breathes and then begin getting to know the posters. There is also a bipolar chat on Friday evenings. This is an amazing site with mostly generous, caring members. I know you'll make some good connections if you can give everyone time to catch up.
