Jack-
This post hasn't been touched on in a while, but I can relate all too well.
Until about 7th grade, kids just percieved me as a "tomboy". I had a lot of friends, and no one thought anything different. 7th grade, I started cutting my hair shorter and shorter. A couple close friends kind of new what was going on, and rumors started lightly in junior high.
By the time I hit high school in 9th grade. There were mass rumors all around school. Luckily I had a senior brother on the football team, who was a big job, who always looked out for me. Along with all his buddies. I had kids write lesbian across my locker, I didn't even dare use the female bathroom, constintly hearing whispers when I walk by. And half the kids doing it were my childhood friends. It hurt, a lot.
I was grateful enough to have a group of friends who always looked out for me. As your friend seemed to do. Kids can be cruel, try and hold your head high, high school sucks for transitioning.
I was grateful enough to transfer schools to a big city. Where I enrolled as a male, and only the principal and my social worker knew the deal. I can't even explain to you how much of a relief it was. Hang in there bud, things won't always be this hard.
