@SillyOldBear and
@Waves and
@Livelife - I wish I could make things better for you guys. Do you feel you have any support from friends, church, or other organizations?
My own mother (who was abusive and is still difficult, although I certainly acknowledge she was going through gruelling circumstances herself) had the opposite experience.
Once she retired at 65 and got away from her horrible employer, she was able to move to an apartment near a large seniors' center and she proceeded to build a social circle there. She took up painting and acting (she had previously been an actress and taught drama to her ) and appeared in several comedy plays put on by the seniors' center. At 83 she lives in an independent-living residence, has many friends (at least casual friends) and plays bridge and Scrabble. She is lucky to have enjoyed good physical and cognitive health. She is also fortunate that my brother and I help her and visit despite the past and continuing difficulties. She's isn't very close to her one grandson because my brother and his wife basically kept him away from her (which I don't entirely agree with but I do understand why). But she has a pretty good life now, and she was able to benefit from the insane inflation of Vancouver real estate prices to be financially comfortable.
I think if that seniors' centre hadn't been there she might not have had nearly as much success socially (and many of the people she knows in her current residence also were regulars at the centre). It's ironic how circumstances make such a difference.
