AITA for being Non-Binary?

I'm Non-Binary and first of all I would like to clarify that my family knows it, they don't have any problem, but some my "friends" do have problems, and l don't know why.

I decided to tell them that l was Non-Binary and some of my "friends" started saying that "You are NOT Non-Binary!","Only TWO gender EXIST", "YOU ARE JUST TRYING TO GET ATTENCION", "You are just CONFUSED" and more...

I felt very sad, I didn't expect them to tell me that, those words Hurt me and l started to cry, l left the place and went to my home.

It may sound crazy or weird l don't know how to say it but this people start to send me messages insulting me because for WHO AM!

So people from Reddit, what should i do?
