i stopped all the drugs a while ago. and yes talking to people on drug related forums about my problem they all say is the weed. i have also considered that i have a mild bit of ocd im always the one out my mates to be assed to clear up and definably prefer space to be clutter free but not to the extent that i worry about it.
i have spoke to my mum about seeking medication, but they are in the business of selling drugs. and not sure where a good mental health docter is, from my mums experience there all pretty crap. im trying to cure it all myself without relying on drugs. an when i dont think about it i do stay happy. but recently i have defiantly noticed my thought pattern being very random at times and looping.
smoking weed can cause all sorts of problems,paranoia,anxiety,panic attacks,loss of memory and all other things,this is probably what has caused all your symptoms and because it has scared you you are stressing about it.Have you been to the doctors about getting help with the drugs,i know you said you have stopped but you probably need a bit of help with itas your body with be detoxing.
oh and i forgot to mention, since this 'attack' i have stopped all drugs completely. my normal smoking has increased but am trying to slow it now as i have calmed my thought pattern.
