3．和老师交流有助于改善自己的学习；
4．探索适合自己的有效的学习方法。
注意：1. 词数100左右；
2．可以适当增加细节，以使行文连贯。
Dear__Jane，
I am sorry to hear that you don't do well in maths and have lost interest in schoolwork. Personally，maths is difficult for most students，so there is no need to feel too bad. At this moment，you should cheer up and find ways to reduce your anxiety. Why not go on an outing with your friends or find time to listen to your favourite music? If you can talk to the teachers who you respect most，they may give you some advice that helps you to improve. Probably it's time for you to explore a new learning method which is better and more suitable for you.
Anyway，I hope you can rebuild your self-confidence soon!
Yours，
Li__Fang
