Everyone is different, but I find labels to be comforting and important. I learned this years ago when my son, who was born with something "different" enough to cause him to struggle in school and socially, was finally given a label - Aspergers/autism spectrum (this was when it was an unknown thing, the very beginning of the autism explosion, but my son's diagnosis led to my mom and brother's diagnoses). Instead of being upset or grieving, I found that having a label for it, a name, gave me comfort and relief, and even a bit of happiness. It meant I wasn't alone. It meant that someone understood it, and there was someone else out there experiencing what I was experiencing.
The same happened when I finally found my own label: bi-gender. I'm both afab femme woman and transmasc guy. It's like being genderfluid, but with only two gender identities. If genderfluid is like taking a train from LA to NY, with all the stops in between, perhaps getting off to experience some other cities along the way, or even doubling back to visit them again, then bi-gender is like taking a non-stop flight from LA to NY. I spent most of my life anxious and dysphoric, hovering somewhere between my true genders without understanding why, and the realization of what I was, plus going on HRT to do something about it, I am now earning nice frequent flier miles being my true self.
