I have also lost most of my hobbies and I'm living in an area I don't know well. The things I do is primarily solitary. I honestly this is going to fit most BPDs particularily as we get older. When younger, we tried to be social and be part of a group. Now, it's more like to h*ll with it.

I used to belong to a bowling league that I enjoyed quite a bit. I don't know if you could do it with your hip or not. It wrecked havoc on me with my messed up knees. If you can get over the social phobia, I'd recommend something like that.
