Not sure if this'll help your situation, but I did something equally dumb when I was back in high school. Clicked on my own ads, got banned from AdSense, etc. (Luckily, it didn't affect my other Google services at the time.)
Recently, however, a Google AdSense sales rep reached out to me trying to sell me on AdSense. I explained the past situation and that I was "banned", but this sales rep was apparently able to get that lifted and get me back into the program. I never ended up using AdSense, but I now have an open account that isn't blocked anymore. Might help in your situation if you ever run into a Google sales rep.
