Is it normal to feel like you're faking it?

Hi guys! For context, I'm hyperfem presenting ^-^!

So I've been wondering for a while if it's normal to feel like you're not actually non-binary/GNC. The way I dress and the way I like to be addressed sometimes leans more feminine, and it makes me feel invalidated as an enby sometimes cause I feel like I'm not "playing the part" right. I just wonder if this is normal cause I can't get this feeling out and it's making me really down. :(! I'd just like some encouragement or advice or really anything to give!
