My 2 rich brothers don't help me, the judge me, are abusive to me, put me down and treat me like my life doesn't matter. How can I cope?

I have two brothers also. I am committed to caring for my Mom at home and they are constantly arguing that we should put her in a nursing home. It hurts. She has become like a child now and I'm the mother. I wouldn't stick my child in a nursing home. It's just the way I feel, so I have to ignore them and do what I thilnk is right. Stand your ground, is what the visiting nurse tjold me when my brothers were giving me a hard time. It stuck with me..Stand Your Ground
