Very bad thoughts

I dont know whats going on. I dont know if its OCD anymore. I know it was in the beginning. Ive been through a lot of trauma and had one little scary thought of killing my sister 4 months ago that has blossomed into this giant idea of me being a serial killer and wanting to hurt everyone (I never had any social issues growing up but I have had some trauma). Recently I’ve been having urges to just give in. And my mental images have been horrible and I can’t stop checking if I like them or not. I think I’ve convinced myself I have. This morning I woke up a shaking mess with an urge to unalive my family and when my mom left for work I was alone with my sister and couldnt stop vomiting uncontrollably. I dont know if i’m upset because I cant hurt anyone and I want to, or if I’m scared and just want my old life back. I was an avid horror and gore lover and now I’m convinced I want to do the things I’ve seen in the movies. Someone please help. I’m ready to check into the psych ward.

I’ve been triggered so bad this week I’ve had bad anxiety and feel depression coming on. Last night I had a thought oh let’s plan it and I immediately thought why would I think that and started crying bad. I’ve had these thoughts for 7 months I really don’t know why I’m having these thoughts, if I knew I would work on it. Like people say has something happened in your life for you to have these thoughts and nothing has happened, it all started off from what if thoughts , like “what if I’m a psycho” because I saw this fb post saying introverts are more likely to become psychopaths and it all spiralled from there I started getting thoughts about harm towards others and myself. What do you think guys should I treat it like ocd or do you think there’s something seriously wrong with me.

I have religious OCD and the thoughts have been becoming really bad. I’ve been hitting myself punching myself screaming quietly if that makes sense pulling my hair out talking to myself nonstop. I can’t even hang out with my family without doing these things or going to another room to do these things, these thoughts of overtaking my life I will always be Christian God is most important to me and I’m so scared because these thoughts are terrible. They’re disgusting they never ending. There’s always something going on in my mind. I don’t understand. I’m scared. I’m turning into a bad person. I don’t wanna dishonor the Lord God, I don’t know if this is just OCD or something else.
