Just moved my Mom into assisted living due to recent hospital stay. She says she's lonelier there than being in her own home with no one visiting..She's 85, dementia, chronic uti's that currently is requiring her to have a Foley catheter. It tears me up when she cries because she wants to be in her home.
Please don't feel guilty. I have a feeling you looked at all the options and chose the one you knew was best at the moment. I hope your mother settles in and starts to enjoy things there. I hope she makes friends she can spend some good hours with. If her old life was not working well, this gives it a chance to work better. That is what we all hope for.
