Hello Missy Di: I see this is your first post here on PC. So... welcome to Psych Central.

Since you posted this in the BPD forum, I take it BPD is something you were perhaps diagnosed with at some point in your life? I'm sorry you are feeling so lonely & sad. Hopefully coming here to PC can be of some comfort & support.
Since you are a bit older

(I'm 70 as well)

one additional forum, here on PC, that may be of interest to you would be the Seniors' Lounge. Here's a link:

I hope you find PC to be of benefit.
