Well，sometimes we look upset， maybe because our boyfriends cheat on us？Will I go banana if my boyfriend cheats on me? HELL YES. But I will kill him son of bitch first. And then I will get over him.[Smilling Face]
go banana:发疯，生气
what will upset me again？Someone ate all my cookies, and I was left with nothing.
What if I didn't break up with my boyfriend, and I kept seeing him. I would be mad and upset too. Because, I know that he will be late for our date because of his stupid games. Eventually, we will have a fight with each other, but do we really need to argue about such trifle things?
trifle：小的，微不足道的
What else， someday，I might get sick of my work, and I want to quit my job. Well, SLEEP ON IT. I can't afford myself.
sleep on it：再想想，再考虑一下
Maybe I am upset because I am having a disagreement with my roommate. I feel like I don't want to have her come over ever. Oh, It's her house too. Now, we have to resolve our arguement.
其实就是咋回事呢，我和室友吵了一架，我这辈子都不想让她再来我家了，奥也是她家，那好吧，现在我们必须和好了。
resolve our disagreement：解决矛盾
Also, would you be sad and even tear up while you are cutting an onion? LOL, I know it sounds so weird. BUT, I DO.
brand-new：崭新的
