Garlic, someone like my mother, posting on a forum like this would be massively enabling for her and possibly dangerous for those around her. It would take a year for me to explain exactly why, and blow my identity out the water at the same time, suffice to say, it can be very enabling for people with disordered thinking to have a willing and believing audience that validate their disordered thinking.
when respondents on problem threads posit the idea that the person under discussion might not be NT, it isn't with the aim of diagnosing that person! It's offered as a possible explanation for the bizarre things that are happening to the OP. For the OP to consider, not the other person. To aid comprehension.
Maybe this is made more difficult because we’re possibly talking of two totally different things. You may be talking about relatively “tame” online diagnoses. And I am talking about a downright irresponsible ones. A “gosh your partner doesn’t sound totally NT, I would be encouraging him to see a psych” type of reply, I have no issues with. It’s the same thread where people regularly pop up with “your partner obviously has xyz personality disorder, he ticks 6 of the 9 boxes for that PD. Leave the bastard. Your life and your kids’ lives will be made a living hell if you remain with him” that I disagree with.
I’m also not sure if I buy into the “to aid comprehension” part of this either. If my only knowledge of PDs was what I learned on mumsnet, well it wouldn’t be much of an aid, as very few accurate things are ever posted on here about PDs. If I was trying to aid someone who suspected that their partner may be suffering from a PD, or just wanted to explore that possibility, there are plenty of good books and websites I could point them to.
And also on this same “aid comprehension” part. When I first started to suspect my husband wasn’t quite like most people, I went to my GP (also DH’s GP) who I have an excellent relationship with. He spent best part of an hour talking with me but refused point blank to even go near a possible diagnosis. He said something like “from what you’ve just said maybe he could have any one of 10 or more MH diagnoses, or maybe he has none”. I then went myself for a few sessions with a psychologist, just hoping she could point me in the right direction to read about, study up on, and she said the exact same as our GP. She wouldn’t even rule things in or out. She, like our GP, said he should go to his GP and ask for a referral to a psych. That was the only thing they both agreed on, based on what I had said, they both agreed that it probably was a good idea for my husband to seek psych help, and my suggesting that to him wouldn't be pushy.
Now if GPs and psychs won’t even go near diagnosis territory with a wife they know fairly well, face to face, with enough time to explain in enough depth, well there must be a very valid reason for that.
