Any GID I probably experienced was always masked by a physical 'disability' that had me in and out of hospitals and doctors offices through my teen years. I have scoliosis, and had to have a full spinal fusion with titanium rods, with a couple revision surgeries over the next few years. I was too pre occupied with being "the girl with the messed up back" and pretty much re learning how to use my body, to notice any trans type thoughts for years.
I was finally able to deal with my scoliosis and move past it, when the depression got worse, and I started in on drugs and alcohol, and self harm. My college room mate finally convinced me to go to a therapist, where I was diagnosed with borderline personality disorder. No surprise therapy didn't help at all. They tried to put me on drugs, and I refused to talk to my therapist after a while.
Jump through the process that everyone knows, and I'm finally happy with myself. drugs and alcohol are strictly a weekend social thing, I've been depressed way less, and havn't hurt myself in years. Its amazing what a binder and mens dress shirt can do for my mental health.
