I FEEL SO BAD UGH

I was clipping my sons nails because they are super long and sharp, he was dead asleep from eating and all of a sudden he flinched as I was pressing down ad I cut his skin on his thumb a little. I feel so bad omg. He only cried for like 2 seconds

It was bleeding a lot, I put water and alcohol and a bandaid on it.

Omg I just feel horrible..
