Pocd and uncertainty

Please someone help me... I need advice... and Im spiraling and im triggered... My pocd keeps saying that my worst fear of unknowingly cybering with a minor has actually happened and it's really triggering the hell out of me... I feel so horrible...My pocd keeps saying I "unknowingly erotically role played with a minor" when idek if this actually happened or not... this was nearly three years ago... (september of 2021) for context we were erotically role playing on an 18+ discord server, and then she suddenly stopped responding, before leaving the server shortly after an unknown time... im so freaking anxious and scared... her grammar was fine at first, but then as we were going on, she kept making errors like "boxer" or "then" instead of "than"... my pocd keeps saying that I "UNKNOWINGLY EROTICALLY ROLEPLAYED WITH A MINOR" when idek if this happened or not... three people told me she sounded like/is a young adult... chatGPT tells me she sounded like a teenager... I genuinely dont know what to believe anymore... (these two photos are from her account, and the beginning of our conversation... I hope she wasnt a teenager... I really hope she wasnt...)
