Okay, I don't know why you think you're not valid, but I'm gonna try to cover several topics some of which might apply.
If you're gender non-conforming (I also apply this to femboy and crossdressing), that's valid. Gender representation and looks don't determine your gender, and clothes are just fabric that has a certain gendered connotation.
If you're trans, you're valid. Trans people have always existed (we have historical evidence for that) and it's never been a mental illness. We also have some evidence for the medical validity of a transgender identity.
If you're questioning, that's valid. It's totally normal to be unsure, and at some point you will come to a point at which you will feel comfortable, no matter whether it fits a certain label or not.
If you're non-binary, that's valid. Those binary categories of male and female are made up. They have no real basis, they're just a social construct.
If you're gay/lesbian, that's valid. People of the same gender are indeed hot as heck.
If you're bi/pan, that's valid. It's not a bad thing to be attracted to multiple genders. That's totally normal and not impossible at all.
If you're aroace, that's valid. You don't need sexual/romantic attraction or a partner to be a valid human being.
In general, if you don't harm anyone or yourself with your queerness, you're valid. Don't let anybody tell you otherwise. I love you all and I wish you all the best.
