Apparently, they (sadly), seem to be suffering from (I'm NOT an expert on this, and could be mistaken) severe autism and/or obsessive/compulsive behavior and/or learning difficulties and/or mental illness and/or the beginnings of dementia.
I concur. In particular, I detect no malice or intent to derail or annoy anyone, just a deep need to find answers, but difficulty expressing the question and accepting an answer. I wish I could help.
I even tried to help them understand via a few private messages, but had to stop and block them, because of my own frustration at the communications difficulties. I could detect myself losing patience, and that does not help.
I do feel compassion, because the root cause is an affliction; but – and I am saying this as someone who has required psychiatric help themselves for recurring depression – classicsamus87 themselves are the only one who can seek help to try and deal with the communications issues, and more importantly, the core issues causing them anxiety and the need to repeat the same questions in an effort to get emotional closure.
Personally, I consider
cognitive behavioural therapy the same for your mind, as going to a physiotherapy is after a physical injury. I don't know if it is applicable to classicsamus87 or if some other form would fit their needs better, but my point is, there is still a lot of misunderstanding what this kind of help is, causing many to reject such help for no good reason. I myself would have fared much better, if I had sought help a decade earlier than I did; and am still paying the price for that error. Do not be stupid like I was, please.
