Lost my Go Card

I had an annoying day yesterday. I left my Go Card on the bus, along with the black leather disney card pouch I kept it in. I got to the door of the bus, and couldn't find it in my pockets or the pouches on my backpack, and the bus driver was getting annoyed, so I thought I'd just get off the bus and pay the fine for not swiping off, but then once off the bus, I couldn't find it anywhere, so I assume I must have dropped it under the seat I was in or something like that. I had about $20 credit still on it too, plus the deposit for the card. Grrr.
