validation of nonbinary identities

T
Idk who's in here but I've some vulnerable little questions for you and idk why I'm shy as hell in this room but it's a thing I guess so I'm rambling????
.
I guess I'm really searching for the opinion of nonbinary humans. They/them humans. But im also just lost and anxious and looking for all the insight I can get???
.
Anyway. 
How do you validate your gender? To yourself I mean? Not for other people. Or maybe for others? But like what things do you do to feel more like yourself? 
.
I'm looking to find some, cos as a pretty femme XX-Chromosome baby, I'm misgendered a lot. Which- whatever- but it makes me really anxious and shakey and just writing this I'm getting all tonguetied and embarrassed and shakey and idk I feel too fragile about it. So I'm looking to find some ways to find validation within myself, for myself, by myself. 
.
SOS?

Peace&Love,
