For the past few years I've been developing a tendency to replay past social interactions over and over in my head. I analyze virtually every aspect of everything I said to the person, until I latch onto one or a few stupid things I said or did. Then, against my will, my mind replays these stupid things until an intense feeling of shame completely envelopes me. The very particular embarrassing incident becomes entrenched in the forefront of my mind, and ALL of my time for days or weeks thereon is completely governed by trying to take my mind off of the incident by compulsively repeating certain phrases or words, or by aggressively obsessing over my other obsessions (which in turn worsens those obsessions and turns them into maladaptive vices rather than healthy coping mechanisms). The moments in which I DO forget about the embarrassing incident are brief and are shattered by the triggering of the memory, which makes me feel like I've just gone down the drop on a rollercoaster. I feel such incredible humiliation. I can't sleep because the repetitive replaying of the memory gets way worse at night and I become very sleep deprived. I'm unable to concentrate on anything else except briefly, not even reading, movies, games, anything, because I'll think of how STUPID I am for doing "that thing" and become dominated by compulsions to forget the thing. There's no room in my head for anything else.
This happens almost every time I hang out with someone, especially if I'm drinking. Granted, drinking makes everyone say stupid things and I know some of things I say or do ARE factually stupid, but rather than cringe and move on like most people would, I become crippled by extreme shame, unable to think of or do hardly anything else for days or weeks. The incidents I obsess about are usually related to me making people feel uncomfortable, me seeming like a narcissist or a selfish person, or anything that proves the fact that I'm an absolute social freak (I kind of am, I've been diagnosed with Asperger's and Schizotypal personality disorder by two separate docs but idk which one is correct as they both have so much overlap). It could be something as benign as how I might have annoyed someone by sharing way too much personal info (as I often do), or something more serious like how I have random emotional meltdowns when I'm drunk and sometimes end up breaking things (this is rare though). And while these incident usually ARE at least mildly embarrassing, the level of shame and absolute self-loathing (often to the point of being suicidal or overdosing on drugs/alcohol to get rid of the thoughts) seems way out of proportion in retrospect.
It's ruining my life. I don't read or draw or do much of anything like I used to, because I can't concentrate on anything with this constant nauseating sense of utter humiliation and degradation.
For instance, right now I'm replaying last night's incident where I said something about sex that I think sounded weird, and now I'm convinced the person I was talking to thinks I'm a creepy sexual freak and now all I can do is periodically yell, hurt myself, or obsess over a different obsession.
What type of OCD/anxiety does this sound like, and should I seek help? I'm afraid of not being taken seriously.
Thoughts? Insight?
