I’m not proud of this but it was an accident

My daughter was having an epic meltdown and flailing around, and she almost whacked her head on our hardwoods and a dresser. So I grabbed her wrists and she was still flailing, so I was grabbing pretty tight to try and restrain her. I left a mark 😭 I am so sad and she was too. I just feel like total crap, I feel so low. Has anyone else ever done this? Is this child abuse?
