It's okay, Rottingteeth (interesting name), if you didn't have it when you were a kid. Some people don't and some people do. I have met a few people who didn't really think they were TS until they started to all of a sudden clue in.
I'm fairly typical, however, and I had gender issues as a kid. I was taken to the doctors who recommended to my mom that I she should encourage me to do boy things and so on. So, I went through scouts and the whole thing. When I was 12 and hitting puberty I and a male counceller do things with me (activities, etc) to help me focus on being male.
Later in my teens, I put on make up and dressed privately. Although I appeared at school, from time to time, with womens clothing (usually taken from my moms closet) and I'd be picked on for that. I'd put on make up sometimes, but get beaten up for it. All of that wonderful stuff. I didn't know what it was called or why I was so "weird" and why I felt this way. I ended up with few friends and keeping to myself mostly. We once had cable for a short time, and I remember seeing "transexuals" on TV, and they were treated like freaks. despite that, I knew that this was a clue.
I got pretty determined to transition once I left school. I had this whole plan set out. It was going to be wonderful. But, it didn't work out that way. I left home and ended up living with a bunch of guys for a while and working. So, I hid things for a bit and talked to the church about my feelings. They felt that going on a mission would help me be unconfused and be more male. My family really pushed for me to go, so I did. While their they sent me to councelling and tried to give me medication. It didn't work, and I only got more depressed. I was in the states for a year for that.
When I came home, I was pretty messed up and was in and out of hospital for a while. I then got off the meds and started to put my life back together. It was hard.
I then came out again to my family (around 22-23), who strongly disapproved. My mom suggested that "I wait until my grandparents die, at least." I lived with my brother, who constantly made fun of me and tried to embarass me in public. At this time I left the church, but they were coming to my door a lot because my brother invited them.
I tried looking for help, and at that time I was going around as Acadia. I had no friends and I was very lonely. There wasn't a lot of information out there and I couldn't find help. I tried to commit suicide, again (a re-occuring thing in my life).
So, then, after that and picking up the pieces I went back into hiding, again. I tried to look male for everyone else. Meanwhile, I worked on a lot of issues. I went back to school for a time. Then I started making friends. I co-ran a publication for a while, and made more friends. I fixed a lot of things in my life and I was setting things up so that I could have a support network. It was a lot of work. It was a lot of recovery.
Then, when I was 27 I became public. I had wonderful friends that stuck with me and supported me, and then I eventually found a local trans group where I met other trans girls for support. It's been a long, long road, and I'm going to be 29 soon.
Life is much better now. I finally feel normal. I'm very happy. I'm glad that I finally did something. Not all of my family is accepting. My brother didn't talk to me for nine months, but has now started to talk to me and has seen me a couple of times (although I'm pretty mad at him because he's putting old pictures of me up on his face book and referring to me as his "brother.") My mom has accepted it. My grandparents have counted me as dead to them, and have tried to keep me a secret from their friends and other family members. My dad has just started to talk to me and and has actually seen me for the first time in a year and a half (but hasn't told my half-sister, since I'm the family embarrassment).
My roommates are amazing. I live with three other girls and they are sisters to me. They are my family. And their family has accepted me 100%. And I have so many friends that I consider family, too. It's a wonderful thing and an amazing feeling to feel that I have that kind of support. That people love me for who I am. It's awesome.
Anyway, that is my story in a nutshell. So, it's pretty typical. An interesting story, but a lot of people have interesting stories. And you have your own story, too, Rottingteeth -- it might be different, but it is just as valid.
