Why do I feel like crying but I physically can’t?

I can’t stop crying. My thoughts are going insane, they’re so fast I can’t keep up. I want to tell everyone around me what’s happening (my family doesn’t even know about my OCD). I can’t seem to resist compulsions today. I’m freaking out. I want to give up. I feel like I’m suffocating in whatever is going on. I feel like I need to go to a hospital. I don’t know how to ask for help. I don’t feel okay. I don’t understand this at all. It feels like I took some random drug. I’m really scared I’m sorry, I am so panicked. It’s embarrassing but I feel so desperate for help right now I feel crazy

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 had the biggest emotional breakdown of my life. I don't even understand why, but because of something that bothered me the slightest bit, i started yelling SOO loudly and bad at my parents: "YOU DON'T CARE ABOUT ME!" I threw some things, i even ran, tried to leave the house, and i ran to my room, i hit my head and i got a bump and some really bad scratches. Afterwards i felt super guilty, i feel horrible for having made my parents feel this way, and how was it possible that I hurt myself like this? I don't understand why i reacted that way, it's so, soo bad. They hugged me and we cried for a while, but i don't understand, am i crazy?
