Advice for my lifeee

17M || I’ve been diagnosed with slight autism and adhd since I was a kid, however it has seem to affected me a lot more, relationships are hard, I’ve dm’d over 140+ people on a dating app and struck out on practically everybody and keep getting unlucky. And I’m made fun of constantly, I don’t understand so many things and I can’t get better at stuff no matter how hard I try and I don’t know what to do, anyone have any advice?
