I'm more confident in myself since coming out. I feel I have better understanding of my thoughts, of my emotions, I feel like I relate to people better, and for the first time in a while I don't feel I'm trying to impress anyone. Likewise, for the first time I am seriously considering my future and not just going through motions. Internally, I have never felt more confident in myself and my beliefs.
Conversely, since transitioning, I'm more nervous when I am in social settings. I always fear that someone may recognize me from years ago, my voice may not pass, someone may see some masculine feature to my face or body. I'm worried that if I don't pass well enough it could be made fun of by bigots or assaulted. Socially, I'm a nervous wreck and I do my best to just stay calm enough to not attract attention.
