nicked babies finger

I literally feel SO bad I was trying to cut my 8 weeks old finger nails and I accidentally nicked his little thumb and now there's a tiny little blood blister and he was crying so hard for a couple minutes. He's fine now doesn't even act like it happened but I feel so bad! I live thousands of miles away from my family and feel like the worst mom. I'm so happy to be a momma and have my sweet smiley little boy but sometimes it feels kinda lonely and I feel like I'm not the best mom when I try so hard especially when little things like this happen.😩
