Heya! I'm so glad you felt good about that pronoun change. Thank you so much for sharing the beginning of your journey here. And it is your unique journey so it's going to be different from everyone else's. Don't you worry about a thing.

As for age, I didn't understand that I was transgender until I was already over 50 years old. But once I got there, so many things in my life made way more sense. The journey takes a great deal of patience and a lot of self care but it is so worth it.

Whenever I get that certain feeling of gender euphoria now, I know I'm doing exactly what I need to be doing in the moment. It sounds like changing your pronouns may have been that gender euphoric moment for you. Learning how to express oneself when one's idea of oneself is still coalescing is not easy. Take your time. Take it from me, there's no rush and you aren't too late! I wish you all the best! :)
