First of all, I totally understand your feeling now. I have also met this kind of problems before. However, It is your own issue for not lending money to Angela. You don't have to feel upset. Although you are good friends, you both have your own life.
On the other hand, if you have spare money, you can also lend to her. The only thing you need to do is to ask her to write a receipt. In my opinion, if you are really close friends, she will pay your back soon. I guess she must be a good girl, too.
sincerely yours，

不知道妳們考試的具體格式和要求，所以只是按正常通用的樣子寫了壹下。但我比較擅長的是議論文，這種不大是我的長項。但應該問題不大。有什麽問題妳可以追問。修改也沒問題。
