Proud of you!
It is not easy to do what you have done and the fact you have a) done it and b) able to reflect on the ups and downs the successes and the challenges shows what a tremendous amount of strength you have. As you said, you have lived a large part of your life essentially as someone else and someone who handles life differently. It's a readjustment period but from where I'm standing you are doing a tremendous job of doing it. I have no doubt it's not always been easy or fun and I'm sure there have been times you've either doubted your ability to continue or felt "fuck it" and wanted to drink again, but in those times just try and reflect on all you have done. Because it is a hell of a fucking lot.
