She is mentally and physically healthy minus arthritis aches, occasionally forgetful but other than that she does very well. She's always lived on her own until 8 months ago she had to come live with us due to a bad fall she had. she has fully recovered and now wants her apartment back. I feel bad that she mentions this every single day. I don't know what to do - I feel that at her age she should be with family.
People are good at covering when they are in decline and their abilities aren't as good. If she is able to do all the things, she needs, then I would at least arrange some in home assistance for her cleaning and laundry.
Sometimes seniors don't realize that being on their own is not really feasible. An evaluation of her needs would help clear that up.
Do you have her Power of Attorney? If she insist on returning home, it may be out of your control if she's mentally sound though.
Do you know why she fell? Often falls indicate a decline and another one will occur soon afterwards. I'd try to find out if she has a balance issue, weakness, etc.
She can't remember to take her meds, so I have people come in 2X a day to give them to her. I handle all of her business and take her to the doctor, bring her food, help her bathe, do her laundry, take out her garbage, etc. etc. But she's very happy to be "on her own". Haha!
If your mom wants to try it and her mind is good enough to handle most situations, maybe let her try it. But know that you'll probably have to move her back in with you (or to a facility) before too long.
