Im 16 years old and i never did any drugs ever. I smoked weed 5 times maybe, but i never inhaled it so i never got high, and i was feeling and seeing fine. Then once i inhaled a bit and got a little high, but after that i was fine and my perception and vision was fine. A week later i smoked a lot more than I could handle and for really really high.(First time getting properly high) Ever since then my vision or like the way i see everything is off, its not right. You know when you look at something for a long time you kind of go into a daze and your not really concentrating on that object anymore? Its like that for me all the time, like visually the way i see everything around me if different, i can still think and everything like before and i can concentrate on something but its just visually how everything is, my brain perceives it differently than it used it. One more thing is i dont know why but i do feel a bit dumber. I am now getting very depressed because I just want things to go back to how they were, I want to be able to get the grades I used to get 90+, and make my parents happy. They do so much for me and I just go f**k my life up by smoking. I also want to tell them but I just cant bring myself to do it, i feel so bad and dont want to stress them. I went to the doctor with my dad and he couldnt quite understand what was happening to me, he made my dad leave the room and i told him i smoked weed 4 months ago, he just told me not to anymore, and he still didnt quite know what the problem was, my dad suggested it was my eyes so the doctor referred me to an eye specialist, but I feel like this is my brain, my mind and my eyes together. I really dont know what to do. I started sleeping properly now, and i started taking vitamin B12 everyday which is said to help focus and memory. PLEASE HELP ME IM ABOUT TO KILL MYSELF
