I concur w/ skibum. I completely buried a lot of things - memories, sense of Self, awareness, etc - starting at around 6 years old. It is possible to get yourself back, but it takes time and a willingness to uncover & deal with a lot of discomfort. I've been working at it for almost nine years now & am still uncovering memories & parts of myself. While that sounds dismal, it's not from my point of view. Each one is liking waking up to a beautiful day where I know I can do whatever I want. Supposedly, the longer you are in that state the harder it is to undo, so from my perspective you've "only" got 12 years to recover. You can do it. Get help if you can, try different approaches, but you can do it...
