My sister appointed and assigned me as her POA for all her affairs and care when she was first told she is beginning to suffer dementia. We both are over 60. Her monthly check comes in her and my name and I'm the one that has to make sure all her affairs including doctor visits are in order which has severely limited me from working full time. Often times I do not have enough money to make it through the month. How can I get financial assistance for caring for her.
