How do I gain my popularity and make my father and Mr. Cooper proud of me again?

You are a bright kid. I can't relate to your life, but I can tell you are bright. Don't worry so much about impressing people. People are always going to expect something from you. If you know someone is bad, you need to try and resist the urge to look up to these people. Trust me. You are young and smart. If you focus on becoming a better person, you will eventually be rewarded. You are 15 and this post is one of the smartest posts I've read from anyone. Don't waste that brain of yours. One of these days you will be grown up. Mr Cooper seems like a strong guy, but those people are never happy deep inside. It's all about long term happiness.
