紧张和累的感觉

在心里中，很多人认为累的感觉和紧张感觉是相对的。太多能源有时会造成紧张感觉，降低能源会造成累的感觉。本人认为两个感觉不会同时所在，反而还是可能的。昨天，我感觉非常紧张，甚至失眠几个小时。早上来喝一杯抹茶还觉得特别累，连学习都集中不了。既然是礼拜天，再睡几个小时，但是已经昨天跟朋友约到时间见面。所以礼拜天又紧张又累。

In psychology, a lot of people assume the emotions of tiredness and anxiety are opposites. Anxiety sometimes comes from too much energy, and too little energy makes one tired. One would assume both emotions can't be felt at the same time, but it's actually possible. Yesterday, I was extremely anxious to the point that I lost a few hours of sleep. Even with drinking a cup of matcha in the morning, I was still pretty tired, I couldn't even focus on my studies. I wanted to sleep a few extra hours because it was sunday, but I already arranged to meet my friend yesterday. So my Sunday was anxious and tired.
