i can say that my bro was at the very least trying to act insane. he said he heard voices and missed a whole day with no memory. people had a microphone in his throat. he believed people we're conspiring.
early signs, you start feeling immense guilt. you want to see someone for the last time. you are becoming quiet and introverted. you don't take a shower. you get so depressed that you feel like you have to laugh, which is actually a good thing. i'd say rent a good movie comedy.
