Honestly man, I know exactly what your going through. I'm still going through it a year later, aftr a bad experience on some pressed pills.
Last summer I had a horrible trip on two pressed pills, that I had flashbacks about for months. I was rolling previously to this, about twice a month averaging maybe 20 pills in 4 months? Who knows. Anyways I was fine after all these rolls until I had this one bad trip, and since then ive came to so many conclusions it would blow your mind. I was convinved I had catastrophic brain damage from that roll, mainly due to my contanst panic/anxiety symptoms along with my insomnia, but then about 7 months post I got drunk and rolled again and since that night my insomnias gone, im much more down to earth and my anxietys simmered a bit, even though its very prevalent still.
This made me think, if my symptoms were surely due to brain damage then how would rolling again cease them? Then I spoke to a neuroligst who said I had PTSD and depression and it all started making sense. This brings on Depersonalization from overstimulation, its your brains defense mechanism from something thats too overwhelming to process. Ive read quite a few studies lately showing that monekeys given 2.5 mg/kg twice a month for 4 months have NO signs of neurotoxicity, and another study showing SERT densities in CORTICAL regions (the outtermost layering of your brain) returning to control levels with abstinance, but this is from heavy use. Your no where NEAR that, so rest assured your brains fine physiological, but psychologically youve got some problems to work out. The BEST advice I can give you right now, and i SERIOUSLY wish someone could have told me this back when it first started, is DONT try and figure out why and start reading all the brain damage studies from MDMA, and propoganda, because itll fuck you up SO hardcore you wont even believe it. I spent 7 months researching EVERYDAY, and its made my recovery SO fucking slow its unreal.
Your brain rewires itself all day everyday, thats how we evolve as people, and develope out personalities. Ever though this event has FUCKED my life up, i'm sure if I come through it ill be a better person, but as bearlove said it becomes a part of you, its called trauma. Even though yours doesnt seem to be as bad as mine, so please dont make it anyworse than it is, youll regret it.
Anyways, DP is a scary fucking thing man, and I HATE it. I feel fried from it, im not the same person anymore, but it IS curable. Just distract yourself, reading helps me SOOO much, work out eat right, take some St Johns Wort kira brand, and try not to analyze your mental processes too much.
best wishes to you
