I learned that you are feeling sorry and upset because of losing the basketball game. It's not easy being in your situation， and it's normal to have these feelings. Anyway， don't be too hard on yourself.
You know， basketball is about team effort. It's never just one person's fault. What matters is that you should learn from the games as well as your mistakes. Besides， you need to think about how you can do better next time.
As a whole， teammates should support and believe in each other. Why don't you sit down and communicate with them？ And you could promise that you will spare no efforts to better your skills. If all of you pull together， you're sure to win the next one.
