I can't tell if I'm skinny or average?

I know for sure that I am not fat. I don't know if I'm skinny either. I'm a size 0-4 (depending on the clothing store), but whenever I look in the mirror I ALWAYS think my arms are too fat and my thighs are too fat, so I feel like I look really average. I'm 5'5 and 109 pounds. People sometimes say "you don't eat, do you?" but I think it's only because they are fatter than I am... what do you think?

And once when I said, "My back is so bony!" to a friend, she said well yeah that's because you're skinny. But I don't think I look THAT skinny. I think I'm average at best, but people tell me otherwise... My BMI and my clothing size do as well.
