I think that's disassociation. If I get engulfed in thought I have trouble recognizing myself in the mirror and sorta phase out- it gives me really bad anxiety when I realize I have it. It can go from "that's really me?" To "oh shit I am a human that exists"
aaaa yeah that's pretty much me rn :\ it's making me think about life and stuff and it's freaking me out lol
Oh jeez. I get it a lot during existential crises too- I only know stuff from experience, but you could try to "ground" yourself?
Like- do something physical or something that reminds you that you're "here". Might at least distract your thoughts a bit.
Disassociation or body dysphoria? Sometimes though I will almost feel like I'm having some sort of out of body experience? Like my body is someone else's and they're puppeteering while I'm forced to watch... I get anxious when I look at older pictures of myself. Last time I actually cried. I used to have long hair and seeing myself that way just feels disgusting to me. I look at her and think to myself "That's not me!"
yikes man that sounds scary ;;; that's kinda what i'm going through right now honestly, like nothing feels real and i'm just kinda going through the motions of life i guess :/
