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.
，I hope you can rebuild your selfconfidence soon!
