Is it normal i'm starting to want people out of my life if they don't get me?

I feel like I've put up with people judging me and putting me down for too long, and I can't endure it like I use to. As a kid you have no responsibilities, so you don't let it effect you because you have a sense of security in your life. When you're older you have more worries, and the last thing you need is people putting you down and doubting you. People in my life are decent people when they want to be. I know people aren't perfect but some choose to be bitches. I ask simple questions, and I'm aggressively given the answers. I have hobbies and interest, and people find them weird. When in reality, its really normal as fuck. People are sometimes offended by things I say, but will offend me all day, and aren't apologetic about it. I'm not weak but it seems like when I defend myself, only when I defend myself, I'm made out to be an ass. I avoid confrontation as much as I can, try to spare people's feelings, but I'm tired of bottling things up that reflect me in a negative way.
