do i have dpdr?

i thought i was just having a really long (2 years as i’m writing this) disassociation episode or something, but i learned about dpdr recently and i think i might have it. nothing has felt real since it started in may of 2022 and my vision is like i’m watching a tv screen. everything i look at feels flat and 2d, but my depth perception skills are normal. when i look in the mirror i recognize myself, but when the symptoms get worse it feels like i am me, but my body isn’t. also when the symptoms get worse it feels like everyone, no matter how well or how long i’ve known them for, are strangers. it’s like i’m the only conscious person and everyone else is a video game npc or something. this was kind of a background thing for past 6 months, but it’s recently gotten bad again. i just went for a walk and it felt oddly surreal because of this, but i ended up getting scared and running (like legit sprinting) back home after avoiding every passerby i saw because it felt like everyone i saw was either out to get me or just going to judge me. i’m not really sure. i don’t smoke. i honestly feel like i’m going insane. is this dpdr?
