求翻译：我有一个问题，需要你的帮助。我员阿里一直认为我在学校是很受欢迎的，但我刚刚发现我的朋友们正在给我最好的朋友筹备生日聚会，他们却没有邀请我加入。除我之外我们班每个人都被邀请了，我不知道为什么。我记不起来我做错了什么，我很苦恼，不知道该怎么做。你怎样看呢？你能帮助我吗？是什么意思？

I have a question, need your help. Ali always thought I was in school I was very popular, but I just found my friends are preparing a birthday party of my best friends, but they didn't invite me to join. Everyone in our class except I was invited I don't know why. I can't remember what I did wrong, I am very upset, don't know what to do. How do you think? Can you help me?
