Q-tip incident

I was cleaning my daughters eat with a q tip because she had visible ear wax. She's only 17 months old and she was moving around too much so the q tip accidentally went to far.. Next thing I know her ear is bleeding. I took her to the doctor but I just couldn't bring myself to tell him it was caused by a q tip. He said that she probably scratched her ear but that her eardrum is 100% fine. I still can't help but feel like a terrible mom. I've been crying non stop because I hurt my little girl...
