Can confirm. It got better when I stopped thinking about labels because labels don't matter. I still look up labels, but I've stopped actively trying to find one. I go with the flow: I describe myself as whatever it feels like - sometimes non-binary, sometimes transfem, sometimes enby transfem. This makes it easier to find a label. Not thinking, but trying them out without trying to find one.
Well, now my problem is that I think too much about transitioning, which is still better. But also trans imposter syndrome. Not everything gets better, but hard trying to find a label stops you from actually finding one and it is an additional thought in your head.
But I don't think that was your question. It's just overwhelming. I was relieved, but also scared when I realized I was actually trans. And the weight of dysphoria and trying to figure yourself out makes school and everything harder. I hope this gets better soon.
