I am very worried about my 78 year old mother. She and my father, who is 84, live over 8 hours away from me. They have always been very health conscious and fit. Their lifestyle was a contributing factor of my father beating cancer (caused by Agent Orange/Vietnam) last year. When I would speak to my mother on the phone, I attributed her confusion to the aging process. When my father had his cancer surgery, I stayed with them for a rather long period of time. She would be fine in the morning, but as the day progressed, her personality would change and at times she became very aggressive. My father admitted that she was abusing prescription drugs, such as oxycodone and others. He also said that she was high when she fell down the stairs the prior year and broke her arm. We discussed this at length and he put the medications where she could not find them. He was adamant about not involving my brother or sister and he does not let her drive. Things were going well for quite a while, but I knew instantly that she is abusing again when I spoke to her last week. My brother and sister have no desire to discuss or deal with this, even though they are aware. They tell me to let my father handle it and I agree to a certain extent, but I am terrified for both of them.
