Do talk to someone you trust. If you can talk to your parents, or one of them, do. Be honest, let them know you are scared and you need help. This is important, keeping it to yourself is potentially dangerous and over time so self-defeating. The sooner you can start to work on positive skills the better, the more open you can be, the more opportunities you have. I am getting old now, and wish I had spoken to someone when I was young, but I don't know that I could have even admitted to my own fear and need, you have courage. Don't be afraid to use it.
