I feel lonely and unwanted by the ppl I want, but I don't have it bad enough to complain in real life

I'm 19f, never been in a relationship, never had a guy interested in me, I've never been asked out or approached. I have a few close friends but I feel like most of them are unreliable, even my 'best friend'. It's not even about a romantic relationship, I just want human connection that is genuine and special, but I feel rejected by almost everyone that I tried to connect with. I try to put myself out there, to be myself and look approachable, but I feel like I'm invisible to the ppl I want. When I try to make the first move I feel ignored or forgotten. Everyone already has a special someone so I I'm not even in their picture. All I want is to have someone special too. Im not tik tok pretty, but I'm attractive, I'm fit, I have cool hobbies and interests, I dress well, I have strong personality but definitely not a bad one, I'm confident in myself, I'm devoted and I love strongly, I deal effectively with my mental health by myself, I give space and but I can also give affection. I have flaws but they are not deal breakers. WHY DONT THEY WANT ME, WHAT DO I DO WRONG?
