I don't want to be Trans, but I wish I had been born a girl rather than a boy, so I think that means I am Trans. There have been many times I have thought "why can't I just be happy as I am?" Some times I can put aside my inner feelings, of wanting to be a woman, at other times nothing else matters.
I know this will sound trite, but there is a journey you have yo go on, one of self discovery. To learn who you really are inside and how best to deal with that person. Once you know that if you decide you don't want to transition, then it doesn't make you any better or any worse a person, it just means that you have decided how you want to live your life.
How do you start that journey? I think most people would agree that finding someone you can talk to about how you feel, and is familiar with transgender issues, is a good start.
