Blamed for money I didn't steal!?

Has she been checked for Alzheimer's or Dementia? This type of behavior is a sign of Alzheimer's they start acting as if everyone is stealing from them and become violent and such. You should mention that to your parents, it sucks when people don't believe you though. I say just sit down and meditate or pray that the truth will come out. Don't stress too much about it, as long as you know you did not do it.
