  1. One would think that erotomania, aka expecting that other person is ifatuated with you even their obvious “disinterest, marriage or financal status” is more common in men, but we rather normalize it, call it “friendzone” and blame women for it.

  2. I suffer from exploding head syndrome and I get it even when I’m not just waking up or falling asleep. I can feel a buzzing run up the back of neck, it gets right into my head and then I hear the loudest explosion and if I have my eyes closed I can see a very bright flash. I’ve had it all my life. I also suffer icepick headaches and sleep paralysis.

  3. why the hell is a graphic from the movie split the picture for DID? The term Multiple Personality Disorder was changed to Dissociative Identity Disorder in 1994 to better reflect the actual reality of the diagnosis first of all. second, Split was a psychological thriller that gave DID such a terrible stigma and reputation. It was not at all an accurate representation of DID.

  4. also borderline personality disorder should be on here tbh. it’s terrifying and it’s considered the most emotionally painful mental illness to live with, or even to watch someone else go through.

  5. another condition is called disjunctive cognition- and its more of a sleep mental disorder that I happen to have.

    its where the people (AND ANIMALS, AAAH!) in your dreams don’t have faces but you still know who they are. Eef…

  6. I definitely have misophonia and it sucks because almost every repetitive noise irritates me, sometimes to the point of insanity or violence, only if I can’t get away from it or get it to stop quick enough! Chewing loud, humming, and lightly singing to a song will drive me nuts!! Even if they’re not making a noise but doing something that would normally make a noise I don’t like bothers me! I hate always being agitated constantly

  7. can yall maybe actually research DID and rewright that portion or something? and maybe not use an image from “split” (which btw, is a very offensive media to people with DID/OSDD, as someone with osdd, like… bruhhh
