I live in a Dallas suburb in a "55 and better" community. Some folks here are in wheelchairs, but they have their dogs and take them out for walks -- lots of people have dogs here. The "senior" communities usually have elevators, and there are all sorts of services you can get to help out. One gentleman here has an aide for 8 hours a week, and a nurse three times a week. The aide does light housekeeping and takes him grocery shopping, or will do the shopping herself if he is not up to it. The best part is you are in a community of people who are generally from your generation, so you are with people you have something in common with. There are more singles than couples, and there are lots of social activities and clubs and inhouse entertainment. The apartment community bus takes people to the various stores and supermarkets and local doctors each week, and there are special trips to museums and plays and other events, plus the senior center is a few blocks away. We are also on the bus line, and the bus will come into the gated premises if anyone needs to see a doctor in Dallas (we have excellent medical facilities here with all the teaching hospitals). The residents are very helpful toward those here who need assistance. My husband and I are in the younger end of the spectrum here, so we lend a hand when someone is in need. I volunteer to walk dogs when the owners cannot, and I will also baby sit when they need to go out. There are a lot of people who will do this, especially for a cute Yorkie
You should think about this type of community for yourself. The one we're in is for low to moderate income. There are also a couple of really nice, newer complexes in the area that cater to people with more income/assets and are top of the line. Several provide chef-prepred meals three times a day if you want. You can do a lot of searching on the internet.
So if you have the resources, you are not stuck in this nightmare you're in now. Just be sure to get an elder-care attorney on your side, so no one can have you declared incompetent just to get at your money. This happens in the nicest families, and it even happened in my own family.
One more word of advice/caution -- don't tell anyone what you're doing until you see that attorney. You don't want to show your hand and give anyone time to prevent you from doing what you need to do. Also, if you share the computer you use, and even if you don't, make sure you erase the sites you've visited so no one sees what you've written here.
Feel free to PM me if you want to talk privately.
