I’m so devastated.

This is my second corn snake, I’ve had her for a year and she turns 2 in November. I’ve never had an issue with her getting out, but I have recently moved her to a bigger cage (a month ago) and she’s gone. Not in hides, not in the substrate, not in the enclosure. I tore apart my room, looked in every shoe, clothing, box, etc and I’m just devastated. This happened to my first corn snake and I have never seen her again after she got out. I’m just so scared it’ll be the same for my baby. I feel like a chunk of my heart was ripped out. I feel like a horrible owner, that I didn’t do enough to prevent this. I made sure there was no way she could get out and she did. I set up a trap with a camera, bunch of clutter in one area and a chopped up mouse on a plate with blood stained paper towels next to it to help spread the scent to hopefully attract her. I’d get the heating pad but it’s raining and I left it in the garage where her old tank is stored. I feel hopeless.
