Why do I feel like I’m never skinny enough no matter what I do?

Why do I feel like I’m never skinny enough no matter what I do? I don’t ever really eat meals, just little snacks throughout the day, I constantly compare myself to others and the people I see on social media, even though I’m 18 now and weigh 10 pounds less than I did when I was literally only 14. I don't know why I have to hyperfocus so much on my body every day.
