Hi, gender is confusing, trust me.
I had a similar problem to you quite recently, I identify as Genderflux which means I switch between a gender (female at my case) and agender but some say non binary as an umbrella term. I am most of the time agender. I am also lesbian, lots sexuality and gender discoveries!
I know it sounds cringey, but you’ll find out when you find out. Sometimes finding a label can help and provide you with a sense of knowing.
If you are non binary, I know it’s hard, but don’t be afraid to tell others, as it may seem like you are copying them to yourself, but majority of people will not think that. If anything they will think that your friends coming out persuaded you to be brave and come out to yourself and others too.
But to be honest, you don’t need a label, you are yourself and coming out doesn’t mean your any different. A label can provide a sense of relief, but you don’t need one to be who you are.
Researching genders if you do want a label can be helpful, but I do not recommend quizzes as they are very inaccurate at times.
Hope you work out what you are soon.
