Nothing causes a meltdown for me... except certain kinds of people. On two occasions in my life I have been harassed/latched onto by codependent, corrupt and abusive people. They harassed me sexually and also subjected me to long discussions about themselves (interpersonal abusers, by the way, are often codependent). On both occasions, I couldn't stop or limit my contact with these people, because they were influential or had an "IN" in the social network of professors at school. They didn't listen to me when I tried to get them to leave me along and sought me out. One of them (a professor) actually stalked me using access to my computer records at the college to get information about me and my schedule.
On both occasions, I eventually (after several months) had a meltdown and started blasting the college administration and the individuals responsible for ignoring the harassment, with emails detailing the offending behavior and the school's corruption and negligence in ignoring the harassment and mistreatment of students. Both colleges had record of zero enforcement of student complaints of sexual harassment or discrimination, and covered up the misconduct of professionals toward students.
At present, I hate people like those two people who harassed me. When I come across anyone remotely like them, I cut them off, quit my job or do anything possible to avoid them. I will start becoming agitated and resentful. and extremely aggressive in attacking the other person, if they don't leave me alone. I think I have developed a disorder that is often co-morbid with Asperger Syndrome: Oppositional Defiant Disorder (ODD), that develops in Asperger people who get harassed or mistreated too much. I will argue with and attack harassers that try to push me and I will also blow up in someone's email inbox if it is their job to act on complaints of harassment and they don't.
Mostly, I hate Dr. Dennis Healy of the University of Maryland, College Park. His girlfriend on the side (he was married) became jealous of me and harassed me.
The people who harass me, who cause these meltdowns in me, are narcissists. They lie and posture really well and everyone believes them while they hide their sadistic abusive side, and pick on targets they think are powerless. Dennis Healy's girlfriend was like that... having sex with a lot of men at once and being a different person with each of them, and cornering me and harassing me. She unloaded hundreds of hours of talk about her mental problems and sexual schemes onto me. After some time of being exposed to that, I lost the ability to process and became low-functioning. I think that too much exposure to these scheming abusers and their thoughts, disrupted my ability to process reality coherently.
At any rate, I hate people like that... closet abusers, harassers and people with complex social psychological problems. They "crash" my system and turn me into a low-functioning autistic if I can't limit or stop their harassment of me.
I also hate Dennis Healy for lying to me when he made false promises to protect me from any harassers that I couldn't handle on my own. In retrospect, it seems pretty obvious to me (and must have been obvious to others) that he was only angling for sex with me. When he didn't get any and got it from this woman, who was having sex with anyone who had connections and would do her professional favors, he just forgot all his promises.
So I hate people like the two harassers who targeted me, who were both sexual predators with mental problems, and people like Dennis Healy, who support and enable closet sociopaths, and ignore the abuse of closet abuseres, so long as he himself is getting something out of his relationship with the abusers (like the sex he was getting from the woman who was sleeping with everyone).
I hate them with a passion. They are evil. I will erupt in people's email inboxes if one of these closet sociopaths and their enablers comes near me.
