I’m ugly crying right now

We have a 6 month old Maltese and I cut his hair it was getting kinda matted so it was time and I accidentally cut him a small cut under his belly next to his arm and I feel like a monster I’m crying so bad it was an accident I thought I could do it I’m never doing it again and just going to the groomers, I cleaned it with alcohol and added some neosporin but god I feel so so bad like I wish it happened to me instead
