LOL I think it is very comical that she pooped in your closet! Its like a little note... "Come and get me!! Or I will poop on your stuff!!"
She is somewhere just waiting for you to find her. Try not to panic. I know it is really hard. I had a snake escape last week and I had a mini panic attack. Luckily I found him in about 20 minutes in a box under some papers.
Get on the ground and crawl around like a snake. Start from the enclosure and work outwards. Keep doors closed if you can and try and shove something in between the gap on the bottom so the snake can't get out of the room.
Check shoes, boxes, clothes, books, speakers (subwoofers), computers. I don't often find snakes near something that is warm. They are usually somewhere that is snug and they feel safe.
If you are in the process of moving, your house might be a little messy, correct? Try cleaning up and going through every belonging you have. You will find her eventually.
I've noticed you either find them within the first hour, or it takes a few days. I hope there are no gaps in your flooring or walls where the snake could escape into the house. My house is sealed up tight and all my vents are on the ceiling so there aren't many places for snakes to hide. On the rare occasion that one goes missing, they are found the same day.
