I have been coming out as bi/pan at school and am getting ready to come out as trans soon and have run into some issues. First of all before I can come out at school I have to tell my father that I'm trans which I am terrified to do. Second of all I've been having issues with having to explain what pan is. I don't really know how to explain nonbinary genders to people since I don't have experience with it and a lot of kids have never heard of it and it's gotten to the point where I get frustrated and say I like who I like deal with it. And a random excitement thing on gender is that today I had my first meeting with the social worker st my school she helped my friend through the coming out process and while I haven't told her yet it's a big step in the right direction.
I'm happy to hear that you got to talk to someone who can help you. Usually when I explain pansexual, I say, "hearts before parts" or I say that pansexual people don't see gender. That's just what has worked best for me.
