I feel like I shouldn't complain, some of you guys on here have it REALLY tough with mentally and/or physically ill parents. I am lucky, my 81 yo mom is healthy and active. That's part of the problem, really. My wife and I are very much loners, always have been. Our best 'date' night is steaks and a movie - at home - and we like it that way. That's why we get along so well, we are both introverted and extroverts make us a little crazy. I don't think we realized that Mom would talk, 24/7, about anything and everything that enters her mind. "Time to make some coffee now!"; "Guess I'm going to have a banana!"; "Going out to get the mail!"...that sort of thing. In addition to this, she's VERY passive aggressive. We are accustomed to saying what we think when we think it, asking for what we want when we want it, and are very unused to someone forever asking "Wouldn't you guys like it better if the coffee maker were over HERE?" "Wouldn't it help you if I would organize under your sink?". This is constant and we are about to go crazy. NO, we like the coffee maker where it is, thanks and NO we don't need our shelves 'organized', thanks. Our new constant phrase is "No mom, thanks, we don't need for that to be done". We have tried to make her feel useful by mentioning some things she CAN do to help, but that is usually met with resistance. She's also wanting us to go places and do things with her that we just have no interest in. She lived alone prior to this and went out on her own all the time to make friends and be social. Keep in mind that she is completely physically able to be out by herself, so that's not the issue...would be a different story if she weren't. Sorry for the rant but we could really use some advice from anyone who has experienced a similar problem. We HAVE tried to talk with her, nicely, about how we just really like to be left alone most of the time and she says that is a "cold" and "unnatural" way to live. Uuggghhh. Nooooo, not for us it isn't. No children living with us, I'm 46 and my wife is 60. She has grown kids living in another state, I do not have children so at least that's not an issue! Again. .sorry for the rant.
If she's really uncomfortable with the way your house is arranged, it might be time to re-introduce the concept of AL or IL.
The idea of finding activities for her is a good one though; sounds like she's fairly mobile, so she could find not only activities in which to become involved, but charitable work as well.
Meals on Wheels needs help delivering meals to homebound seniors; they might need assistance in packing the meals as well. Hospitals sometimes have need for people in gift shops; the VA in our area has someone to go from one area to another in the outpatient building and offer reading material to patients and family waiting to be seen.
Food pantries need help sorting and assembling (and perhaps organizing, which your mother might enjoy). Some senior centers also need staffing help.
Animals shelters might need help working with the animals; some libraries have programs by which children read to therapy dogs; an older person might be appropriate as well if she has a soft, comforting voice.
There are groups that make crocheted, knitted and quilted items for military personnel, for babies in NICU units.
She could also call 211 and ask which charities might need volunteer help.
I'm not clear - has she actually sold her house?
