I'm nonbinary, I've always loved trans people, but never really had an opinion on myself being it.
Eventually, out of nowhere I was hit with dysphoria in 2020, and I decided it was time for me to come out/express my emotions to my partner + some others.
Gender is cool because at the end of the day, it doesn't need to be as excruciating and serious as some take it. Try different pronouns like a hat for a little, try it on yourself in the mirror. You don't need to change a thing about your physical appearance, you can just see how you feel even referring to yourself as such. Don't like it? Then you can stop!
I remember I was feeling horrible one night, I didn't want this, I wanted to be "normal". Deep down i knew the root of my own problem. I whispered "i am a woman", and immediately felt sick to my stomach. It was a huge turning point for me. After I had come out and started publicly using different pronouns (they/she), I noticed people would keep purposefully using she over anything else. That was it for me, I felt so uncomfortable, I felt upset, I felt angry and then I realized, there's no turning back for me anymore. Being that upset over something like that solidified what I needed to be brave and comfortable about and accepting this part of me.
I didn't want to live my life out as you said either, but after accepting my emotions and feelings, I've never felt happier.
If you can, try to minimize the "problem" for yourself. Your relationship with your gender only needs to be between you and yourself. I don't take it seriously anymore, I understand in the future maybe I'll turn around and feel okay as a woman, maybe I'll keep being nonbinary, maybe I'll delve into being a man, who knows? It's not a big deal to me, and i don't care what anyone else has to say about it in my family or in my friendships. Their opinions on this matter are irrelevant, the only person you should care about is you here. Take your time, there's no rush.
