My mother is 93 years old and a widow for 6 years. I am her only child. She obsessively worries about many things and is sometimes paranoid. Ie. Someone is taking her mail. She can be very controlling and frustrating. I often have to take a tranquilizer to deal with her. She refuses to take any medication besides Valium and only takes that to sleep. She has no friends as they all passed away. I am her only go to person. I feel very burdened by this.
