I don't understand gender.

IT'S SO CONFUSING. I don't mind people referring to me as a girl, I call myself a girl most of the time but I don't feel like one??? Or at least I think I don't??? I don't feel like a boy either. WHAT DOES IT EVEN MEAN TO FEEL LIKE A GIRL/BOY???? I don't identify as non-binary because I feel like the label doesn't fully fit me, IT'S SO CONFUSING HELP.

Please tell me I'm not the only one feeling this way
