Spot on description.
Started as undistinguishable chatter but during my full on episode it took over my head and was completely audible and at times tried to mimic my own inner voice but I could tell it wasn't.. You can identify your own internal dialogue and the point of origin in your head so to speak, whereas I felt it externally.. Like I was hacked (What'd you do to this guy? - We kept him awake for 3 days. - Oh damn! no wonder ha!)
I hope I'm crazy but as the months drag on, hearing the same old chatter again, commentary on my fuckin thoughts, despite being on anti-psychotics... I'm having a lil trouble here. Feels real but I'm dying to believe it's not. True struggler's..
