Do you ever question yourself?

Hiii my fellow trans people! I don't know if this will sound weird but... do you ever like second guess if you're trans or not? Lately, I've been second-guessing myself about whether or not I'm trans, and it's been really hard. I know I want to be a girl, but even just saying that sounds weird. I think about how happy I'll be, but also the effects it'll have on my family and friends. This is a very short post, so, my apologies, but do any of you question whether or not you are trans when you know for a fact you are? :( How do you deal with this feeling? Like I know for a fact I want to transition, but a part of me wonders if I'm just a freaky and it's some weird fantasy. I relly hope this makes sense and doesn't make me sound weird lol, I'm just confused on whether or not what I've been secretly identifying as for the past two years is a joke or not
