Not for me. My parents. They have been together for 40 years and past few months they have been fighting daily. One is accusing the other of cheating, is constantly threatening "evidence" and for the past few months has behaved strangely. And I mean really strangely: believing that "lovers" are coming through the windows, marking doors with numbers, sniffing toilet paper, using wireless security cameras indoors to spy on the other parent, saying things are being stolen from him, puts padlocks on both exit doors at night, etc. I came to believe that this is either psychotic depression, signs of dementia or delusional disorder. This parent claims not hearing voices or having particular hallucinations, and seems to have no issues functioning in any other area of life and memory is fine. My accused parent has had serious health challenges. I feel cought in the middle because I live and support both of them. Hence, I feel sad, frustrated, depressed. Do not know what else. After 40 years of their marriage, I fear that this is the biggest test for them. And I watch and cannot do much to help them. I have prayed to God, tried to mediate, tried yelling, tried calm conversations, even tried psychics! I am not seeing much change. I do not know what to do anymore. The parent with physical health issues is on the verge of filing for divorce/leaving. The parent with mental health challenge is adamant that he is in the right and refuses to hear out my concerns.
