@PenelopePlum Believe me when I tell you that it doesn't have to be substandard housing and wicked landlords! Do your due diligence! Google is your friend. You can hunt up senior housing in your area. There are probably waiting lists, but my experience has been that if an apartment is offered and that person declines for whatever reason, their name goes back down to the bottom of the list, meaning that the waiting list can move along at a pretty good clip.
It also helps to talk to someone from your area's council on aging or whatever is the equivalent where you are and establish a "relationship" with them, even if only on the phone or via email.
I understand the need for peace. We all deserve it all the time, but most especially at this late stage of our lives.
