Blackout drunk and got home safely(?

I am a 19yr old woman, i have no parental figure to take care of me so i’m kinda free. I only remember getting drunk alone in a random club, after that all dissapeared (I just went for a couple of drinks to forget my life, but it seems i overdid it.). I just know i woke up in my bed, my auntie didn’t noticed anything not even me getting through the door. I’m scared someone could’ve done anything to me or else but everything seems okay… Does anyone knows what could have happened, did my body knew what to do or…????
