Why is my mind trying to turn me into a horrible and violent person?? This has never been me ever, i just want it to stop!!

Is this ocd? I Have a thought or think something f harmful that I’ve gotten intrusive thoughts about - and get a feeling like I want/like it or it would give me relief??? Please tell me that will eventually go away and I’ll get my real feelings back??? Or have I just turned into those things? Sometimes things that make me upset it even feels like I’ll do them just so I can be upset about them.

Does anyone else experience this lingering fear and anxiety because they think they’re capable of hurting someone? It’s killing me. I feel like I’m such a danger. I feel like I’m a predator. I feel like this awful person and I can’t shake it. I want to carry on with my day but I can’t. I don’t feel like I deserve it. I feel like I’ve done awful things. I can’t stop crying.

This may upset some people reading so here is just a warning that these are disturbing I don’t know what to do to make the bad thoughts stop. My mom recently had a baby, my little brother. I wasn’t exactly happy about this pregnancy, but I have nothing against my brother. He’s adorable and silly. Nothing against him. But I feel like these thoughts bug me because what if deep down I do resent him because I didn’t want my mom to have another kid? What if I did act on these things because I hate him? What if I just lose it and do something? It’s all so illogical, I know. Never would I ever want to do that. But there’s times I’m watching him for a few minutes for my mom and my brain just shows me an awful scene of me brutally hurting him or killing him. Or I’ll be holding him and my brain shows me a scene where I purposefully drop him or I just hurt him so badly. I’ll be walking near him and my brain tells me I’m going to stomp on him. It shows me such bad things. I have intrusive thoughts all the time, but this is different because there’s a semi good reason I “could” do it. That being, I wasn’t happy about the pregnancy. And it scares me. I’ve started crying because I was so scared it was going to happen. I have to back up away from him or sit down so there’s no way I can do anything. I feel horrible. I don’t want to hurt him. And I’m so scared I will. But I won’t. I’m hoping this makes sense to others who struggle with this. Because to anyone else who’s never gone through these things I’ll sound insane. And sound like a psychopath. Thanks for reading. Any help would be appreciated.
