Hi 16 year old Anne,
don' t worry about school, family, sports or boys. Everything will turn out fine.
First of all, would you PLEASE stop worrying about the things that MIGHT go wrong. There's no reason. You are doing fine and if you don't stop worrying you will miss the best moments. Some great years are ahead of you.
Maths is tricky, right? Hard to find the right solution you believe? I tell you what? Its as easy as it can be! Just believe in yourself!!! Thats right. Just believe you can do maths and you can. I'm serious. It's that easy. Just believe in yourself. Soon a very nice teacher will tell you so and maths will become your best subject. Just wait!
In the next two years you will make lots of friends, go to some really good partys and just enjoy life in general. You are excited to go to South Africa for a month soon? You will go again in two years and stay for three months. Lots of beautiful things to discover in this country you hardly know anything about.
Sportwise it is also going to be just great. You will finally fnd the perfect swim team and Nico will join you. Together with Jassi you will have an amazing time. Yes, Jassi! Don't really like her? Just wait.
Boys! You'll find one! All you have to do is wait two more years. He's handsome and charming, everything you dream for. You will feel like you are in heaven for a year or two. But, no, I cannot tell you if he's the right one. You won't know for a very long time. Just enjoy today. The last years at school are the best. I promise. Don't worry, be happy :)
