I've read and heard my fair share of complaints from people who seem to feel as though no one likes them for some particular reason or quality that others seem to have and they don't. They say so and so is not as smart as them, or is a bad boy, or taller then them, or a different race or religion, or is more high maintenance, has more money than them, or is skinnier then them, or dresses a certain way that they can't or won't, and the lists go on. Nobody likes you, so what are you going to do about it?
I mean that, what are you going to do about it? If someone doesn't like you, why are you fighting tooth and nail for their approval? Sure you can go back to school, or put on some make-up, or workout more or whatever the thing you think is holding you back, but if whatever those changes are, aren't a part of you or who you truly want to be and you're just doing it to try to get people to like you, you're going to fail or lose yourself in the process of trying to become someone you're not.
You cannot force attraction. Saying things like, so and so should want to date someone like me is such a waste of breath. People like what they like. You..like what you like, so why are you so offended when someone doesn't like you or your personality or your looks and why take it so personally? There are absolutely people you would never date or would probably pass over, I don't care who you are so if you can understand that, then someone not personally liking whatever it is about you shouldn't be such a surprise all the time. You can't decide for someone else what they should or should not like in another human being because attraction is something that is built up in us over time as a result of experience, our upbringing, our exposure to friends and various people and experiences, and cultural/societal/ and even religious norms.
And then here it comes...wait for it...3...2...1...but life is so unfair and blah, blah, blah. Yeah, where have you been? We all wish everyone liked us and who we are and what we looked like, but that isn't the case. This is the real world. Is it incredibly difficult when you aren't "the chosen one," more often then not, yes, and I'm sure you've written loads of questions and takes about your unfortunate circumstances, but this can be that sucky part of life where some portion of society just don't get you or like what you have to offer, but the truth is, it only takes one. And as hard as a pill is it is to swallow, some will never get that fairy tell ending. They just won't, but I can also assure you that life is so much more beyond just having to be in a relationship.
