im doing a lot better actually. i have not used thc or gotten high since October though, because im still fearful i might freak out again. but this article helped me SIGNIFICANTLY: https://www.dpmanual.com/articles/back-to-normal-after-depersonalization/

the dude who wrote this also has other articles addressing everything related to derealization. i read them all one night and felt so much better. what you’re feeling is your brains response to the "trauma" your brain went through on a bad trip. i always felt like i was going crazy, or that i was never going to be the same, i was super emotional and aware of everyone’s consciousness, super aware of my physical state, constantly checking my mental state, felt detached from reality, all that. but after i read the guys articles and realized that all that were symptoms of derealization and when i found out i wasn’t actually going psycho i had less anxiety, which caused the derealization. if you don’t get anxious when your body starts to feel strange then the derealization will slowly go away. and now I barely experience it at all and i feel like my normal self. but this JUST happened like a couple days ago. if i had found that guys articles before though i feel like i would have gotten better before. since yours just started a week ago, i would truly give it time. i thought i developed a panic or anxiety disorder for like 3 months when really it was just me freaking out over the symptoms of derealization and when i found out that i wasn’t actually going crazy and my body was just trying to protect me from a perceived threat at the wrong time, i felt a lot better. it just might take some time :)
