I can't get this one thought out of my head because it's so scary! I feel like it won't ever go away :(

So I had a panic attack a while ago to “kill mom” and I forgot about the thought until a few days later. When it came back I was mentally drained and it lasted for 2 months or more. It eventually went away but it is back. I get other intrusive thoughts but they go away after a hour or so. Why am I stressing over “kill mom” so much. I just get irritated that it won’t go away. I’m beginning to think it’s a different mental illness maybe just anxiety? I’m not sure to be honest. It just appears and sits there and I feel like I’m doomed and a pyscho and worry that I’ll never forget the thought.

I’m tired of thinking about the same OCD thought to “kill mom” it just doesn’t leave. I try to break the cycle but when it’s broken it just sits there and waits to be interacted with. Idk what to do im tired of it. And it makes me feel like a psycho path and I’m tired of not feeling like myself.

Bro I'm scared rn, so there was a compulsion I did like 2hrs ago and I didn't do it properly cuz I kept getting a thought saying "something is gonna come in Ur room and kill you or you will have this illness It triggers me to say it but I froze because I kept seeing like a shadow and cuz I was home alone and it's dark so I didn't answer it 😃 and cuz I answered it late saying obviously I don't want to illness I would rather have the other (half of me knows it's not real), and I prayed 4 times as well cuz I didn't do the compulsion properly I tried doing it again logs if times and 1 hour later I tried again but It still didn't feel right, and now the thought is hurting my body a little and I feel shivery, and I have tried doing the compulsion but it's not working. Why can't these thighs just leave me alone and stop saying about illnesses all the time. And idk how I'm gonna get thru the night cuz I can't get the thought out of my head and I won't be able to do anything properly.
