Is it normal i am experiencing trauma-like symptoms after being exposed to gore
A week or so ago I had joined this discord server looking for some online friends, so I made an intro in the intros channel explaining some things that I always tell people I meet so they don't see me as rude or weird for infodumping or anything (I'm autistic). But then this group of people just start fuckin' harassing me, calling me slurs and shit for being autistic. I do prepare for situations like these with proof that autism doesn't equal stupidity, but they wouldn't listen at all.
I know I should have just left the server or whatever but I just felt compelled to prove to them somehow that I'm not stupid for being autistic. This went on until they, for some reason, sent me an image of a fucking severed head on a table. I only saw it for a few seconds but now I can't seem to get it out of my head. This wasn't the first time I was unwillingly exposed to gore online but for some reason it's the one that stuck.
Sometimes I look in the mirror and see my head and the image pops up again, I self harmed in the shower the other day and the blood made the image pop up again, some nights I can't sleep because the image pops up, etc. I don't know why it's like this it doesn't even feel like full blown trauma or anything, it barely effects my life. I have no idea how this is an issue for me when there are people out there who actively look for these images.
I really want to know if this is normal or not. Am I just weak? Am I just too soft or something? Please tell me.
(Also just fyi I did leave the server STRAIGHT after seeing that shit)
