Welcome to TGH.
This is a safe and supportive space in which to explore your gender identity. Although I’ve only been a member here for a few weeks I’ve been a member of the sister site, Crossdresser Heaven, for several months now. I’m sure that you’ll get a lot out of interacting with everyone, just as I have.
I’ve just looked at the member directory; TGH has 378 members in Arizona, so it’s always possible that someone geographically close to you will get in touch with information about local support groups. That would be a great place to start while you’re still questioning who you are.
Meanwhile, there’s loads to explore. Take your time, settle in, and find your way around 🙂
