I might be a pedophile and that terrifies me

I’m 16m and I saw similar posts and people talked about ocd but I don’t know it might be different, I only started thinking this way after 4 days ago, I was at Chuck E. Cheese watching over my siblings then saw this girl maybe 8 or 10 and thought “wow she’s pretty” or cute or beautiful or something like that it got blur because i kinda at the exact moment started fearing I might be a pdf, so (I know this sounds weird but I really wanted to prove to myself I wasn’t) I started looking at her from a distance and trying to say to myself “you are not attracted to her” and I used ChatGPT despite what people say I felt like I couldn’t go anywhere else, yesterday I was close to dropping it and just saying ocd but when I tried to prove to myself but I thought about a situation in my head involving a minor my heart fluttered or adrenaline rush and that reopened it to me, it also messed with my judgment like I’ll ask myself “will you ever watch cp” (I HAVE NEVER AND NEVER FELT THE URGE TO) but my reaction will be “uh no well maybe like I could see myself doing it” to me the biggest proof and the only proof my mind can’t screw up is that it kicked off 5 days ago and I’ve never had any thoughts like that, I just want human confirmation because I’m scared ChatGPT is just telling me what I want to hear. (Sorry for grammar mistakes English isn’t my first language)
