Marijuana and its effects on my brain.

Hi, I was a heavy weed smoker since July 2017 till December 2017, I used to smoke around 4-5 joints a day. One day, I decided to quit and it's been 9 months since I have completely quit weed but I still don't feel like the same person I was before I started smoking weed, everything seems less intense than before, listening to music doesn't feel same and it feels like I've no proper recollection of my memories from 9th to 11th class, my thoughts have been fixated more on the traumatic time I had from 6th to 8th class, I feel like I've regressed a lot. It's hard for me to live in present reality. I feel less intelligent and a loss of quick wit and the ability to think on my feet, I still don't feel like my sober real self, everything is a bit numb, I haven't experienced true feelings of euphoria or general happiness since I quit weed, plus I cannot cry either. Please, help me.
