Sleep

Regina, you are 15-years-old, why do you think so much? Stop thinking about unimportant things, stop thinking about why this happens, or why that happens. Stop blaming yourself for those happenings. But I know it's hard, I know you will always end up finding a reason to hate yourself, a good reason why people don't like you as much as they like him, her or her.
Stop feeling sorry for yourself, stop over thinking. You need some sleep. Stop thinking about scenarios that will never happen. Those thoughts will only get your hopes high, and one day those scenarios in your head won't happen, and you will be painfully disappointed. Keep walking on the straight path, Regina, just today. Don't try new roads first. Go forward. No turning left or turning right. You need to focus. Stop thinking. Get some sleep. You need it.
