I've been studying like crazy for final exams. I feel like my brain is going to explode!
我为了期末，变身学霸，很努力的学习。 我脑子好像要爆炸了。
need a breather 需要喘口气
lose it 失控，要疯了
burn out 精疲力尽
You need to take a breather before you totally lose it! You don't wanna burn out before your test.
你喘口气吧，不然你会失控的。考试前可不能垮。
take a brain break 换换脑子
hit the books - K书
OK. I'm gonna take a brain break and watch an episode of "I'm a Singer" And then I'm gonna hit the books again!
好吧，我先看一集"我是歌手"，换换脑子，然后再接着K书。
