I know you have other kids and grandkids in the SD area. Hopefully, they will chime in with ideas and options to help you.
I know your condo is owned by your daughter. Sounds like she is planning to sell it.
Yes, look into assisted living places if you can afford to. Not sure what your financial situation is like, but where I live, you can buy a park model for less than 100K and own the land which means you don't have lot rent to pay each month, just $350 per month for HOA which is very affordable. (if I can afford to live here, anyone can!) Lots of things to do here and 6 swimming pools to choose from!
Just another option to consider and you wouldn't be too far from San Diego and your other kids, etc.
