I have dropped meds on the floor before too. I know how fast our babies run to gobble what they think are treats on the floor. It's not your fault. Praise God you got her to the vet right away. Stay busy, doing something that can take your mind off of it. Clean your cabinets, clean out a closet, something to keep your mind and your hands busy.
You have so many people praying for you and little Maya. All you can do is stay busy so you don't have time to worry.
Sending hugs, too!
