If you dig back as far as July, you'll find my posts about how I discovered I was abused as a child. I'm 27. I don't remember much at all about it.
But as far as, "Why now?" I think it's because NOW you have grown up enough that you can emotionally deal with it.
I think that you and I are some of the "lucky" ones, in that we've been able to continue on, relatively normally, in our lives, without the dramatic types of issues of many of the others here.
That said, your question of "Is this normal?" can only be answered with "As normal as possible, considering that some trusted older person took advantage of you, when you couldn't understand what was going on."
My best advice is, first, get counseling. We, on the boards, will all offer up what advice we can, but someone trained to deal with this will be more beneficial. Second, make sure you've got a support system, beyond this place. You never know when your ISP will have a brain fart, or your computer will take a dump, so a real live, breathing friend can offer more than we can, sometimes (hugs, f'rinstance). Third, don't hide from this; deal with it head on. Your mind hid it from you, until you were ready to handle it; the time is now.
Please continue to post here. I find it valuable to vent, or work things out that percolated in my head while at work. Plus, my best friend/support system is on vacation... Heh heh heh!
Take care, bud.
