Lost small fluffy white rabbit named Snowball with a pink collar near the park library in Florence.

I lost my little bunny named Snowball while we were out for a walk in the park near the library in Florence. She's a small, fluffy white rabbit with a pink collar. I must have taken my eyes off her for a moment, and she darted away into the bushes. I'm really worried and miss her so much. If anyone sees her, please help.
