Wow, way to go @janbb & @KNOWITALL. I realized just yesterday that I still have a long ways to go as far as forgiveness, but at least I am conscious that I need to grow in this direction.
By far the best thing I’ve done for myself is deciding to transition. It makes my life a whole lot more complicated, frightening, and difficult than the lives of people who are not trans, but I am happier than I knew it was possible to be, I feel whole, and I can actually be an adult now. I have no regrets whatsoever, although I hate that the world does not want trans people to exist and that most of us have to live in fear and insecurity.
A close second would be staying single for a year after ten years of mostly codependent relationships or relationships of convenience. Learning to enjoy my own company and being OK being single, moving past the feeling of needing to be in a relationship to be happy.
