I felt exactly the same way today when clipping my keets' nails. Pixie decided to go haywire when my mom tried to hold her so I could clip her nails in the bathroom. Instead she escaped my mom's grip and ended up scratching her wing with her nail after hitting the wall, making herself bleed. Luckly the bleeding had already stopped by the time I managed to get the cornstarch. We watched her for a few hours after returning her to the cage to make sure she didn't hurt anything. The only way she allowed me to check anything was to brib her with a Q-tip covered with lemon juice (her favorite treat). She's fine now and sleeping. I was crying like a baby the entire time.
