My younger sister has a headache. How can I help her feel better?

I don't know what to do when I finish secondary school.

I forgot to buy my mother a birthday present.

My best friend likes playing video games every day. We never do anything different. I like playing video games buy I also like going out and doing things outdoors. What should I do?

My best friend is angry with me because she told me a secret and I told other friends about it.

My best friend moved to another city. I really miss him/her.

I got detention because I was late.

My classmates call me names. I feel really sad. I have talked to them but they don't stop bothering me.

It's my best friend 15th birthday party and I don't have anything to wear.

I have a Maths test but I don't understand the topics. They are too difficult.

It's hard for me to make new friends. I'm very shy. I don't know what to do.

My neighbours are too noisy. They play loud music till very late every day.

I've failed some of my exams. My parents would get angry with me.
