Hello.. i have this kind of problem with my thoughts.. i know it sounds XXXXXX, but i feel like i constantly have alot of thoughts that are going through my head nonstop.. like when you hear a song, and cant stop singing it in your head.. thats how i feel, just with my own thoughts.. its hard to explain.. i dont hear voices, and i think im normal besides that.. this problem started after i began smoking marijuana.. and right when i wake up, my thoughts already start spinning like crazy.. what can this be?
