My sister suffered a brain injury about 10 years ago while trying to give birth. My mother and I provide care for her, but my niece (her child) acts out, My mother (who is elderly and has many physical problems of her own) and I are both burned out and I feel like all three of them are taking their frustrations out on me. What really bother's me is that I'm the main family member that helps all three of them yet they take their anger out on me. Some days I get so tired that I fell like just walking away. I even tried to find a higher paying job so I could move out of my sister home. Is their anything I can do to help all of us cope with our situation better?
