Ughhhh I feel so bad!

I clip her nails all the time without a problem, and today I cut one just a little too short and I got the very tip of the quick. She yelped out and it bled a little bit, but not too much.

I called the vet's office and they said to put some white flour on it, which I did. She seems ok now but she's licking her toe/the flour. She's walking on her foot ok and it seems to have stopped bleeding.

I feel so awful, my poor baby. Will she be ok? Do I need to take her to the vet or will it heal on its own soon? Should I be worried? I'm always worried.
