How Do I Come Out About Being Genderfluid When I Already Did?

I told my family I'm gender fluid and they freaked out and said it's a "faze" and I'm "going too fast." After that I stopped identifying as gender fluid. The thing is: I have these fazes where I'm a boy. So, usually I'm a girl.

I like makeup, I have my hair longish (not really) and I wear lots of pink clothing and I feel like I AM A GIRL.

Then I fazes where I'm a boy. I just FEEL like I'm a boy. I just KNOW I'm a boy. I can't explain it. I just know! And when that happens...I dress like a boy, I wear an orange hat, and I act more like a boy. (Oh yes and I hate my girly name)

So when that happens...I'm still a GIRL to my family. It's...weird. But I don't know how to come out to my family about it. How do you tell your family your sometimes a boy and other times a girl??

 

Thanks! This is a good idea. (I'm sorry I spelled phase wrong I made this post and another one late at night and I was rushed)
