Dear Ben
Thank you very much for your letter.I hope I can offer you some useful suggestions.
You said you feel stressed with schoolwork and you have a lot of homework to do so you hardly have any spare time for your hobbies.It will be a good choise to make a list of all the homework you have to do.Then work out how much time you need to complete it all.This will give you an idea of how much free time you have so that you can have some time do relax.
It seems that you often quarrel with you parents.You need to chat with them and get help from them.The best way is to let your parents see you progress.
You said you are afraid of being laughed at when you don't do well in study.Please pay no attention to those students who laugh at you and be proud of your schoolwork.
I hope my advice is worth taking.
Best wishes.
Your friend
