Please help

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.

I’m sharing this bc I need advice or even support from anyone who can relate. If you can’t relate and don’t think you’ll say anything helpful or kind pls don’t comment anything… I’ve been struggling with somethings that’s making me question myself. There has been moments while self pleasuring when I get intrusive thoughts, in those moments it feels like I’m enjoying or even self pleasuring myself bc of the thought. Right after I immediately have an anxiety attack and my HEART drops bc it feels terrible I feel like a disgusting monster :( ppl have told me I haven’t done a bad bc of how intense my guilt and panic are but I keep thinking that MAYBE I made a horrible decision in the moment and the guilt is just realising that it’s just wrong this doesn’t make sense to me because I’ve always told myself that I would never act on this in 1 million years and I’ve been known that these things are wrong so I’m just like constantly questioning myself these feelings and exact same situation has happened two times already I even promised myself that I wouldn’t act on anything beforehand and yeah, I still felt like I did act on my thought during my alone time I’m genuinely convinced that I’m a horrible and it’s even got into the point where I don’t wanna be here anymore and I don’t even think this is my OCD :( tbh

I struggle so bad with intrusive thoughts. They can be so bad that I'll cry because I KNOW that's not how I feel or want to do. (Too embarrassed to say what they're about) I'll constantly try to figure out why I have them, and constantly figure out what they mean, causing me to constantly circle around and around. I had to get on anxeity meds, which helped a little but the thoughts still happen. How do you help yourself with this? How do you know that you're just not some physcopath? 😅
