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!!

I know we’re not meant to ask for reassurance but I’m currently not in therapy and I need help, it feels scarily real and I feel like I’m not anxious or worried over the thoughts. I had stabbing thoughts about someone I care about and I started deliberately imagining them to test myself to see if I hate it or not but instead it felt like I knew how it feels to stab someone and like the feeling of doing that physical action and I swear it is the worst thing I have ever experienced as well I had moments where it felt like It was about to happen or I keep getting this really sick ‘happy’ feeling that I want to do that and I don’t know what that is but it feels incredibly real almost like I was getting a happy feeling or wanted to do that thing and jsut wasn’t giving into it and now I’m thinking I’m actually evil and it feels like I get a pleasurable feeling over the thought of doing that and would want to do it?? Because I ‘like’ the feeling of doing it or it would ‘feel’ good I swear I really don’t know what to do it feels incredibly real I feel like I can’t even say that I’m worried or scared because I feel like I’m lying and actually want it and have evil desires I’m really concerned, I have never done anything bad in my life, I feel like what if through experimenting and imagining the thoughts to test myself I have suddenly discovered I like it because it feels extremely real that I would ‘enjoy’ or like Doing that evil thing and it’s really concerning, i don’t understand I was fine a few days ago and suddenly I’m experiencing this? Is it possible to suddenly become evil i don’t want to be evil, but what if i like it and my desire to not be evil isn’t as strong as this ‘happy feeling’ i wish I can be normal I don’t want any of this please but I swear I feel like there is something wrong with me, I think this is the worst I’ve ever felt, like it feels like I want it and would enjoy it and it’s making me feel really worried but at the same time I don’t even know if I’m worried please help I need advice

Recently ive been getting very scared to even be angry bc of the horrible thoughts I have and it feels even more real when I'm angry or even annoyed. Rn I was not even super annoyed at my neice but I felt a twinge of annoyance since she went up to my face and was yelling at me while I was resting on the bed and I got this image of doing something bad to her and I felt my hand twitch very little. I got nervous and felt relieved when her dad told her to stop screaming for no reason. I've been hyperfocusing on my bodily reactions (mainly my hands or how I'm feeling like did I just enjoy that? Was I considering???) And I've noticed the small twitches whenever I'm mad or annoyed and it's scaring me so bad! Like do I want to act out? Am I holding back??? I used to not even twitch at all when mad and I felt 100% sure I'll never act out but now it feels like I don't know bc what do these twitches mean?, I do know I don't want to ever act out but it's so scary. Recently whenever I feel angry once the argument is over I cry really bad after I'm alone and I pray so i never want or act out. And when the annoyance passes I also feel so guilty and want to stay away. Im scared these are real urges and i research for many many hours to make sure they arent urges or impulses and i also tend to ask chatgpt or here if the anxiety gets so bad 😕

I get these violent urges thats started randomly and now i feel like ill hurt someone it feels impossible to control almost gets me shaking
