The problem you are facing is quite common among us teenagers. As a student of your age, I quite understand you, and I have some advice for you.
Firstly, you should understand that your parents care about you. They often compare you with others perhaps because they want to let you be aware of your disadvantages and help you become better. If you don't like it, you can tell them about your feeling, saying that you feel stressed out. Secondly, you can tell them that you have the confidence to improve yourself in some areas. And meanwhile, let them know that you want to be yourself. I believe your parents can understand you and make some changes.
Hope what I said above can be of some help to you.
My classmates and I are planning to plant trees by the river this weekend. We all hope you can join us. Here is the schedule.
We are to meet at the school gate at 8 o'clock this Saturday morning. Since we'll cycle there and work in the field, you'd better wear casual clothes and comfortable shoes. ①It would be so much better if you could bring some necessary tools. Besides, we'll have a picnic after the work is done. ②Everyone is expected to bring their lunch and share it. We may return at around 3 o'clock in the afternoon.
Would you like to join us? Hope to see you then.
