Firstly, never have to apologize for long posts.
It is better to be understood in full than be brief and leave something important out!
Will pray for peace and safety for you as you go through this time. My own experience in high school was rough, but you're right that having friends helps a huge amount. And having fellow Christians as friends, something I lacked then, is even better. So that's great!
Keep being a light, and you are correct that God is next to you at all times. Which means a constant support and source of strength when things get rough, and as you know they will get rough at times. He never deserts us.
Keep us posted if you need other prayers or to talk! Anyone who has been through the challenges of high school is no doubt happy to chime in and encourage you. Make it the best you can, and in down times remember it is only for a few short years. Good luck!
