Overanalyzing features/pretty but wrong/ancestry

My ordeal with my appearance is so odd. I feel as if it's freaking me out a lot, the thing is currently I don't feel ugly. I've been working out recently, + taking care of myself now since I began to look miserable and puffy so my body itself feels good. <3 Thing is.. I look at myself in the mirror. Dark brown eyes, dark brown hair, full lips, tan, nose that's a bit upturn but a bit big at the front. Okay,, I like how I look. But then I look at my photos, and for some reason I just cry and feel washed. Like especially old photos, when a few years ago my skin looked a bit lighter than usual, my hair was a bit lighter and overall I just feel as if it's all wrong, my face looks morphed. I feel washed and it's this stupid theme that's going on. I see my family, my older sister she has more of a downturned nose, slightly darker skin currently, and has such features that makes me a bit jealous. (She's really pretty ! 😭) must've taken mostly of dad's features with a bit of my mom's, my mom is beautiful as well but I just look hmmm.. not ugly, not bad, just... ??? I continue to analyze my features with many different things, when I was a teen people also compared me to Jenna Ortega (she's also really pretty), now when I see myself I don't really see it as much..? Maybe others still do, I don't know. But I still feel a bit odd, I just want to feel unique with my features. People also say that the more Spaniards you have in you, the less Mexican you are and it scares me a lot. I used to whitewash myself a lot back in the days, and now I can't tell anymore,, my mind tells me I'm colonizing my family lolol. < /3 I sometimes say "You look brown, what are you talking about?!" And then the next I'm like "Oohhh this picture says different... uhm,," This is so annoying.
