Physical and Mental Harassment by Husband

Hello, I got married (Love marriage) in the year 2017 July. Since the day I married his behavior got changed towards me. He started harassing me physically, mentally and acting like psycho. Ex: He himself takes cloth and put in his mouth and shouts for help. He hurt me physically and sleep on the bleed blood on the ground. When we go out, if someone looks at me, he harasses me saying why they are looking at you. When we go to movie if actress cheats on actor, he physically hurt me for that and with no reason. Oh god so many likes these. I am literally facing hell with him. He always abuses me like crazy. Finally he broke my hand one late night and left me on road, I went to my parents home it's been an 8 months for now. Now he came and started harassing me to come with him and threatening me and abusing me. I lodge a complaint on him recently but nothing happen. He came out of station and threatening me now again saying I will see your end. I am helpless. I need divorce from him. Please help me what to do. I cannot be with that guy for a life time. I know he will kill me, I have no other option. Please help me out from this situation.
