After going to a neuropsychologist I've been diagnosed with "class a depression" and "a personality disorder".
Alright, the "class a depression" I'll accept. These fucks wouldn't survive a week in this body, but, whatever. Not entirely wrong. It's also partially a side effect of my meds.
What the hell is "a personality disorder", though?
Mind you, they didn't say what personality disorder, just that there is one. It turns out that carrying a large bottle around is a personality disorder. I'm thirsty, and I don't want to buy those tiny 0.3l bottles every second, so I carry a bottle. The 0.5l bottles that come with a harness are too small for my needs, and the 3l military "water backpack" thing is too big, so I took a rope, cut a piece, and tied it to the bottle. Turns out knowing the hanger's knot and reusing a nice 1.5l bottle for my needs is considered a personality disorder!
The field of mental health uses diagnostic labels based on a cluster of traits that these professionals have agreed are the foundation to guide in the formal diagnosis of a patient. It's somewhat like an "artistic endeavor" IMO, and less so like a "scientific field". In other words, this stuff isn't black and white. Envision ten people admiring an abstract painting inside the Metropolitan Museum of Art. Each could have their own interpretation as to the meaning of the painting. Psychiatry is kind of like that. Studies in the field have shown that if five mental health experts are each listening to the exact same patient's presentation that each of the five experts independently could conclude a different diagnosis.
Thus, don't potentially be rattled by a potential "personality disorder" diagnosis at this stage.
I'm in the states, here experts use the Diagnostic and Statistical Manual of Mental Health Disorders. The abbreviation is DSM - 5. (The 5 represents the fifth edition). Essentially this is the field's "bible". However, this "bible" is merely a guide to help govern the diagnostic tools.
Here is the specifics with your situation. It is extremely unlikely that a competent mental health professional would diagnosis you with a potential personality disorder exclusively based on your water bottle size and your hangman knot. The potential "quirkiness" of having a noose does not come close to meeting the minimum threshold of any cluster of traits for any of the specific personality disorder types, IMO.
Hopefully, you're meeting this professional again, and I'll suggest for you to do the following. First, go in the mind set that this person is not an adversary and can potentially help you to better understand yourself. But, be careful concerning the disclosure of any potential CTB ideas, otherwise you run the potential risk of an involuntary psychiatric hold. Next, bring a note pad and pen. Ask your neuroscientist this, "based on how I presented last time, what led you to conclude that I have a personality disorder". Write down everything he says. These should be "the traits" that led this person to your diagnosis. If this person.says, "your water bottle is too big and you have a hangman noose". Ask them, "what else"? If they say, "that is it". Ask, "what exact personality disorder does this behavior fall under"? Listen closely; take great notes.
I suspect this professional is seeing aspects within your presentation that led to the personality disorder conclusion, but you need to clarify. Ask, "what is the exact disorder."
You need to know the exact disorder this person correctly or incorrectly suspects. It's kind of like your primary physican telling you that you have a broken bone in your body, but with out telling you where in your body your bone is broken. How does that help? Same concept with this generic personality disorder claim, IMO. You need clarification.
Once you clarify the label you can access the DSM -5 (or DSM -4) within most US libraries with any decent sized population base. With Covid, you'll likely need to figure out how to access this through an online library. If your outside the US, you'll have to figure out what your particular country utilizes for it's diagnostics. If within the UK or Europe, I'm sure someone else on SS could tell you what is used for diagnostics.
When you get to this point, feel free to "tag me", and I can guide you through the DSM, if you need assistance.
Fyi, I'm not a mental health professional, but for whatever it's worth, my undergrad was in psych, and I've spent plus or minus 100 hours with five different psychiatrists attempting to better understand my own personal mental health issues and to coordinate a treatment plan suitable for myself. In addition, I've spent 80 hours roughly with two separate psychologists trying to better understand and help myself. Further, I've spent hundreds and hundreds of hours educating myself concerning mental health theories for my particular isssues, manufacturers data pertaining to drug efficacy, reading scientific papers on Pub Med, etc., etc. Don't hesitate to request suggestions.
Try not to let the process or any potential fear overwhelm you. Just stay on your toes about any potential CTB topics. Lots of potential mine fields down that road, especially if your unskilled in your delivery.
If you have questions before hand, let me know, and I'll advise you to the best of my abilities.
And, as an aside, where are all my buddies from undergrad who told me my psych degree would never come in handy? Finally, after all these years....
Take care.
