It sounds like you don't have motivation to change. What do you want out of life? How can you reach those goals?

This is all about mindset (it sounds like you already know that). You have to choose to change, and it's very hard at your age. You have been doing things this way your whole life, and things won't ever change unless you CHOOSE to change them. You're in control of your life and your destiny. It's time to start living like it.
