Dude, rethink smoking weed. I know I just have. I started smoking everyday around march and have now been 10 days sober. I started smoking weed as it made me feel relaxed and made me accept my stutter. But after a couple of months doing it every day, I'm in the worst place I've ever been. You see, when you smoke everyday, there's a chance you'll get paranoid. Just as you say, you tend to overthink your conversations, yourself etc. I started feeling like i was drowning. I was thinking so much about how I appeared to others, insted of just being myself, that I feel like I have lost my identity. I have become no one. I had an anxiety attack which scared the hell out of me, as I was feeling like I had physically and mentally dissappeared from this world. I'm not saying this will happen to everyone, but it seems like you're kind of on the same road. Weed made me accept myself, only to make me forget myself.
