Well you took the words out of my god damn fuckin' mouth. Pretty much said what I believe everyone here wanted to hear.My knowledge isn't special or unique, it's from a combination of university classes, boring textbooks that handhold you through the different maladaptive conditions that can manifest, and work experience. Anyone here is capable of it. If you are genuinely interested in the purely scientific aspects of illness, I would refer you to DSM-5. Be warned, it is 950 pages long, and is a very boring read. Pick a disorder that interests you and read through it. This is the doctor's manual for psychological disorders, lines of treatment, and even what they should charge for services rendered.
I will look at the thread mentioned, thank you, but I doubt I can add to what you guys have figured out already, I can just give you the fancy Latin names.
As I mentioned, he manifests a staggering number of red flags for a number of disorders. He appears to lack empathy, for example, he does not understand why other people feel the way they do. Example : aunt dies. You think: Jesus christ my aunt is dead, her husband and kids must be devastated. He thinks: Jesus christ that bitch died. Who the fuck is going to rent my unit to now, I was counting on that money. I don't have time for this shit. What a fucking bitch.
His world and understanding of emotional concepts begins with him and ends with him. People, to him (I suspect), are not people so much as they are variables, constructs that can contribute to him or harm him. They are to be utilized for gain, and when no longer a positive net gain, they are removed with prejudice. See: tapping his foot looking at the clock, waiting for his parents to die and those fuckers better have left everything to him.
Normal human relationships resemble a sine wave. They have peaks and troughs. Sometimes your friend is a dick and you tell him to fuck off, but you eventually have distance and can process the situation. He is still your friend, you still like him; he is human, we fuck up sometimes. Continue on as normal. You do not make him grovel and beg and shout apologies and expect monetary compensation for his actions. You text him and say what are you doing this weekend?
He does not appear to process emotions like an adjusted person does. Emotions are fluid and change and as you grow older and understand yourself, you understand these emotions and what they represent. For him, I would say they are more of, I guess I would say they are like a rubix cube. Every now and then, he matches up a line of colors and that feels good. Most of the time he's just spinning them in the hopes that they line up, but they don't and that is frustrating. See: his barely fluctuating perpetual fuck off mood. He can process frustration: this is not something he wants. It is a negative experience and therefore a threat and must be expunged. He can process rage: something is outside his immediate ability to control. This is unacceptable and must be violently excised. Cut it out. Get rid of it. Now. He cannot make something bend to his will, this cannot be understood; its doing things beyond what I want it to, unacceptable. Remove.
He requires control in his constructed reality. Lack of control is extremely distressing for even normal people. But for him, his world revolves around him. He controls the narrative, the setting, the pace, the tone. Anything but fawning questions or outright praise is seen as an attack. In his defense, years of perceived trolling will make a person paranoid. He could have dealt with this with self awareness, examination, willingness to adapt, and the ability to understand that he is the common denominator in all of these perpetually growing number of 'detractors'. See: a lack of growth as a person over the years, an inflexibility in persona, unwilling to try new experiences. The unknown is not controllable, avoid at all cost. See: religious adherence to an arbitrary schedule that is set in stone, even though the nature of the platform is he can stream at any point on any day. . He picks when and how he will entertain you, you either attend to him, or you are a detractor. The people that don't know who he is, and that he is a chill, fun, entertaining person may as well not exist. They offer no value to him, so why acknowledge something worthless? Waste of his time.
Persecution complex. If you're not helping him, you're hurting him and wasting his time. See: perpetual victim. Inability to recognize or acknowledge that perhaps his own actions put him in the sitations he finds himself in, and why they're almost always the same issue. Someone plotted this. He did everything right, not his fault (a meme, I know, but seems to genuinely believe it, and reinforces it often).
Inability to process love or affection if it is not him. See: a cold, loveless marriage where they spend the majority of their time apart, one party actively avoiding the other. This is picturesque love in his mind. He owns a house, a car, and a wife. The only time they spend time together is to spend money. When on the couch, silent, resentful watching of other youtubers. This is love. This is marriage. You envy what he has. See also: how he treats his cat. Jasper is a pain in the ass. He does things that animals do. Scratch things. Bite things. Want to play. Want affection. The one and only response he has is to actively punish him with the water bottle. If Jasper was a person, this is the equivalent of spitting in his face telling him to stop. This is paternal love in his eyes. The stuff he does for this cat.
I'm sorry, I sperged again. This is not the entirety of what I wanted to say, these are just the indicators of his illnesses and the video evidence of his actions, and put in a way to easily compare against the baseline of what the standards of maladaptive behavior are.
This is not all there is, there is more, sadly. There is still the compiling of primary issues and comorbidities, and requires a filing under the appropriate illness. This is an interesting way to spend an afternoon, literally dissecting a personality.
I may be weird.
And you say there is more...?
Would you like to go on, possibly? It's very interesting to read.
