I'm 6inches and 5'9 with Scandinavian features and have never had a girlfriend. I'm 18 and feel terrible.
Few people want to be in a relationship with someone who's insecure
Stop seeking the validation for others
If there's something negative about yourself you don't like, change it. If you can't change it, accept that it's part of your character. If someone doesn't like that unchangeable, "negative" aspect of you then they're not worthy of your attention.
