First off, congrats! I'm at a similar point as you, and it's exciting!
And oh my, yes. Coming out is fantastic to a supportive group. I come out to my immediate family and a group of close friends, and it's so liberating having people know. I don't have to hide with them anymore, and it feels great!
Plus there's the unexpected bits of support that pop up from the really awesome people. A buddy who I just told called me pretty and started playfully hitting on me LOL. He and several others have made it clear that this won't affect anything between us and that they're available for support if I need it. Hearing that always makes me happy, each and every time

The more out I get, the happier I am. Conversation comes easier and is more fluid, I'm just comfortable in my skin for once, and it feels good. I'm excited for a day to come when I no longer have to hide at all, but my voice/appearance need quite a bit of work before then
