Hi Randy,
The good news is yes, it really, really lifts a burden from your shoulders. The bad news is that for most people there is not one "coming out", but many. You may first come out to your closest confident, then maybe your family. Then there are the people at work, with all the HR hassles, and then there is coming out to each of your friends, some of which will be supportive and some not so much.
I have been full-time for about a year, and there are still some friends I have not confronted because I think it won't go well. Kind of silly, I know. If they won't accept me, there wasn't a friendship worth saving in the first place, but I am talking about friends I have known for years and it would be painful for me to acknowledge that loss.
In my heart I know that if you have to prune that relationship tree, it will be healthier and more beautiful in the long run, but it is still hard to face. As I once told another friend here, just about everything about transitioning is either (a) hard; (b) painful; (c) expensive, or (d) some combination of those.
With kindness,
Terri
