I hate that nobody looks like me

I'm 20, and as I get older and find more looks I absolutely love, I find it really hard to be happy with my natural face. I'm mixed asian, but I feel like I don't look like other wasians (I guess there aren't many wasians that look similar to each other anyways) but it just makes me feel ugly. I think I'm pretty, but it's like other white girls can like look to other white girls as reference and know where they stand beauty wise, but I cannot do that so I don't know if I'm pretty or ugly. People tell me I'm pretty, but I don't know if I am or if that is something common for girls. I know it sounds silly and I don't wanna look like every other person, and I do have my own personal style, of course, but sometimes it'd nice to know what I look like objectively ig. Anybody else have this issue (or do I just have low self esteem)?
