Outed Myself by accident

I had a friend come in my home and I thought they would wait at my door but they came in and they saw all of my things and writings and drawings about my thoughts on diapers and other people’s judgments and I feel like my world is completely collapsing. I live in a very small town and they didn’t say anything but I know they saw literally everything and I just want to crawl in a hole and die. It’s like my worst fear has come to life and I feel so exposed and humiliated and there is no room for interpretation as I literally wrote about liking diapers and the fear of being called a pervert and I’m scared they will now ruin my life. Do I just let it go and pretend it didn’t happen?
