Enby = N.B. = Nonbinary.

To further elaborate, the reason (at least as it was told to me) that it's the "sound it out" version of the letters is because NB is already used for "non-black." I never heard of that in 30+ years of life, but apparently I'm just not in the right circles to have heard it. The non-binary community does not want to step on the toes of another marginalized group, so the letters became word-ified.
I could be entirely wrong about this. I've identified as enby for about 2 years. I learned of that word very shortly after coming out about it, which itself happened about 2 days after I learned that "non-binary" was a thing one can be instead of just the male/female binary. So if I'm wrong on the etymology of "enby," I hope I will be corrected.

Learned of it shortly before coming out.* Obviously... (wish I could edit these)

Well, there's all different kinds of non-binary, such as agender (neither), bigender (both at once), gender-fluid (shifting over time) and more. In my case, I just never felt right as my AGAB (assigned gender at birth), but I also didn't feel like I felt strongly enough about the other side to transition. I didn't know one could be in the middle.
My first hint was watching Ranma 1/2, starring a male character who is "cursed" to transform to a female body when splashed with water. I really wished that could be me. I also had sexual dreams with someone I liked where genitalia would be used and then exchanged to switch roles. Of course, that's just dealing with the physical. Gender politics/dynamics have always interested me, but I always felt they were kind of bogus. Like Haruhi Fujioka said in Ouran High School Host Club (dub), it's more important for people to be recognized for who they are, rather than for what sex they are.

yeah, that's more or less what I've been told about the change as-well. TBH, Enby has a nice flow to it so I ain't complaining.

that's the mood right there

Feel this on a lot of levels. Gender?... uhh... bluh... dog? yep dog.

Gender?! I barely know 'er!

Fuck bigots, me and my homies hate bigots.

With that said, right on mate.

sometimes it do kinda be feelin that way

Looks great! Also glad you found the courage to come out as NB. As I've done the past 11 years, I support ya 100%.

You are you and that's alll that matters. You being you is part of what makes life such a colorful and amazing experience.

i second that thought if possible :)

i feel like i am but dont really want to be, mostly because it seems/feels boring in comparison to all the others...

It is amazing you can finally express who you are in a much safer light. :)

You can be anything you want to be.

Reject gender normalcy, become Lizard.

I'm just glad to have you here; you deserve to be able to be yourself without fear and knowing that folks care about you:)
