What is wrong with me? am i schizophrenic? or just worthless?

i talk to the voices in my head on a piece of paper by writing down what they say and what i say to them, i see people who follow me everywhere and talk about me and they won't leave me alone no matter what i do! i get a headache when talking to the voices, and end up screaming shut up! let me f*cking think!! i draw pictures of swords, and sharp things stabbing into people with lots of blood, and write down things like the assassin symbol and women's rights symbol, and i used to self harm regularly and now i just do it when it gets out of control. the voices tell me to do bad stuff like punch someone in the face, which i end up doing. but most of the time i can get on with everyday activities and have trust with people, and socialise. but i tend to daze, and gorm, more then the average person about my death or other deaths around me, and i wake up to the voices or the people following me make them stop i just wanna be alone!
