@Jennifer 1967, I'm glad you've still had the pool to float in for stress relief. Do you have any ideas for things you can do when the temps get cooler?

As others have written, there will come a time when you have to draw a line in the sand and say "No!" to your mom and brother. I know you love them very very much, but you have to love yourself, too. And your mom and brother also have to love you a lot. I'm sure they do, but they have to show it a bit more at some soon point. I am assuming that your mom is just a bit beside herself with anxiety over your brother. She will eventually need a reality check on what is the right path forward. It's hard for an adult child to have to act in such a way towards a parent, but there comes a time when the parent needs the adult child's direction. I know my siblings and I had to do that for our father. A sad sad reality as life goes on.
