Totally understandable to be worried about that! I hope coming out to your parents went well. Coming out takes a lot of bravery, but I can promise you it will get a little easier with time.
I can't promise you that you'll definitely fit in with other women, but I can tell you that it doesn't matter. Everyone is unique, and being trans is only one way in which you're unique. I know it sounds trite, but it's true; some women are blind, some women are Latina, some women are left-handed, some women are trans. They're (you're) all women! And in that way, you do fit in with everyone else.
Hell yeah feeling good!
