Hey Lita!
Maybe you could try and go to "baby school" and show them how much you know. Maybe if they realize you already know the class's material, they'll let you go to Junior High. You always said you miss school and you haven't been there for a while now, so even though you are older you still missed material that you will need in higher classes.

You are a smart kid and I bet you'll catch up in no time. Like others said, being sweet is the secret, as I know you, you are a little rebel, so you might have to lay low for a while with the stunts and you'll be fine. Just think about how to employ this great mind of yours into positive deeds.

I bet that your life so far taught you how to stay away from troubles and bullies, trust your instincts and your abilities, maybe one day you'll get to be a doctor like you once said you want to be.
