weed + e

hi,

ive never posted on a forum before so here we go,  i went to amsterdam with one of my mates summer last year and combined E + weed i freaked out big time the whole CEV and thought i was being murdered and dead, anyways i recoverd fine and went taken e and weed seperate after this however i smoked again this send me into a huge panic attack my head was hurting i noticed everything like a tap dripping the noised played in my head for what seamed hours then my eyes felt like the were being poked by somethign sharp. a few hours later i got over it and thought nothing, however the next day i went to the cinema and on the way home i looked at the houses around me which caused me to think i dont know what i can see passed these house i felt lost and alone. i got on the internet becuase i could not stop thinking i was in a depersonalized thought loop lets say, i diagnosed myself with anxiety which i have recetly figured i do not have which feels good, i am getting better now, however i still feel like everything is fake from time to time that i may be in hell and the is eternity, i feel like i need to end it. however i know i will not. how long will i feel like this, just until the weed clears my system?

thanks
