I am in a similarly isolated and neglected place. I know how painful it is.
DH's strange and self absorbed behavior slowly chased off pretty much all of our friends over a long period of time, and we don't have much family. (He has some, but they would only be there for him) I'm pretty much on my own emotionally at this point. Sometimes you don't have a lot of other options. Someone on another board suggested embracing being a lone wolf, at least for the time being. Sometimes that works, other times not so much.
There are probably a lot more people like us out there than we can imagine. The loneliness sucks.
I'm here with you in spirit. Hoping and praying for better and changing days ahead for both of us.
