Awww Joyce, we will definitely send good thoughts and prayers yours and Pixie way. She will be fine and back in your arms in no time.
Ask the vet when you can give her some additional pain meds, should she need them. Maggie was in a bit of discomfort the night of her spay. As soon as we gave her some pain meds, she quieted right down and went to sleep. Hugs to you. It's never easy.
