While Dad knows and grieves his sensory losses, Mom is totally unaware she has any problems. She also can't remember her beloved of 70 years can't see (macular degeneration) or hear. While Dad tries very hard to meet her every need, she gets frustrated, angry and yells at or mocks him. I'm totally stressed out trying to meet their conflicting needs. Being a referee isn't what I 'signed up for'. Can I tell Mom to stop acting like a petulant 2 year old? I don't know how to deal with this anymore and I'm close to burnout.
