I'm 17 and for the last year or so i've been seriously questioning my sanity, and its really getting to me. I dont know what's real and whats not anymore, i cant concentrate on anything, i hear and sometimes see things that aren't there. I smoke cannabis on a regular basis (every day) because without it i feel depressed and nothing seems to mean anything. I'm trying really hard to separate what is real and whats not but nothing seems real at all. I have what other people call 'delusions' about reality and I know its stupid but i cant help but believe them. For example, almost every waking minute i have what seems like outside narration in my head of my voice telling me none of the material world is real and that it is all simply an illusion that i have made, and every day more and more i believe it. It's hard to even type this because i keep questioning the point of even posting here (this is the 3rd time ive tried). The present feeling of being completely alone scares and depresses me, and this is why i just hope the train i get on everyday derails and ends it all. I feel like i don't know anything for sure anymore, except for my own existence.
