Mom has isolated herself with no interest in people or going out. Refuses help. I'm 6 hrs away and work full time. I call but she is accusing my sibling of coming to house and stealing (he is on west coast); thinks I'm divorced (untrue); makes up stories about doctor and surgery (untrue). It is getting worse and it takes everything I've got to call her and listen to these untruths and accusations. Friends have stopped calling because she sounds crazy. SHe lives alone in her home; refuses outside help for cleaning, meals, companionship -- won't let anyone in. Help.
