(NSFW, MINORS PLS PLS DO NOT INTERACT) I think im a groomer.

Minors please do not talk to me. I am 18. I saw a post earlier today on Twitter that said if you talk to someone online and forget to ask their age and they are actually a child irl, then you are a groomer. It was a groomer in question on Twitter that groomed someone by being friends with the victim and sharing NSFW to them, but they didnt know the victim was a child. I hate groomers and I dont wanna be one but I am because I did something terrible. I was on the OCD Reddit searching for reassurance about a weird thing I was attracted to, I wanted know if it was weird or not, and someone came into my dms reassuring me and telling me it isn’t weird. I told them a little bit in detail about my sexual attractions because they asked about what turned me on, because I wanted them to know I wasn’t turned on by terrible stuff. They concluded by saying I wasn’t a weirdo, and then I asked them “you’re an adult right?” And they said no. I thought they were an adult because children dont usually ask stuff like this. I know i was only 3 months 18 when this happened, but it doesn’t justify it. This caused me to have an anxiety attack. I said sorry repeatedly over and over again and told them I groomed them, and for some reason they said I didn’t even though I did. I ended up blocking them and tried to ring my therapist to ask her to report me to the police. She wouldn’t. So I just had to live with the fact that I was a groomer. I prayed to the universe to undo what I did, but it wouldn’t work. I will always be a child groomer and there’s nothing I can do. If you are a child reading this please get away. I block everyone under 18 that I see, I never talk to anyone under 18 in my classroom, and I advise you do as well. I am a child groomer and I dont want to be but I am one. Is it possible to undo my evil?
