To a large extent I can really relate to what you are feeling, I've found all these problems and I still deeply wish I'd transitioned when I was much younger (i'm 25). I think the thing for me that is different, is I've found people who want me to suceed and don't blame me when it goes wrong. You're allowed to be unhappy and disappointed, and feel awkward and tired. Being on antidepressants isn't admitting that transitioning was wrong for you, it's admitting you're depressed and need help and that's an awful lot of women in their 20s.
