I think I have ocd and hocd?

It all started on febuary when I saw this horror movie.the guy in the movie killed his own brother and I said to myself what if I turn crazy and killed my family. I imagined my self chopping there heads of and I got and anxiety attack. I couldnt stop myself from thinking these thoughts.and everytime I think about killing people I feel the need to take a **** every time and went to the kitchen I started standing and staring at the knifes and freaked out cause images poped in my head about killing people.then I few weeks ped by and I felt better these thoughts didnt bother me no more.only on somedays but it only botherd me a little.then on march 20 the thougts started haunting me again hearing gory lyrics from some heavy metal and death metal songs but then it stoped in a coupe of weeks like on april. And itt started again on may when I heard the song angel of death by slayer,when I heard the part of the song that says infamous butcher I imagined myself be a human butcher which almost made **** my pants but then these thoughts went away and I started worrying about becoming gay which freaked me even more out when these thoughts appeared I have never had a stronger urge to kill myself. Thougts just came that I was gay and I kept on saying to myself that im straight and my mind kept on saying why am I lying to myself.sometimes in stores my mind makes me look at guys and I hate it .sonetimes I want to scream or cry in the stores and I shake or twitch in stores. I tried punching or slaping myself everytime these thoughts came up everytime I look at guys I get anxious and freaks me out. So do I have ocd/hocd or am I crazy and turning gay im hope I dont turn gay.
