Invisible anxiety.

Once again, the darkness closes in, and the nightmare I feared has returned.

I talked with Taiwanese in English, but she seemed like it was difficult to understand what I meant. She asked me "What?" "What do you mean?" and "I'm not sure your words." As a result, she started speaking in Japanese.

Her actions reminded me of a bitter experience, in which I had lost the courage to talk with someone in English.

Then, my team leader said, "Are you sure to talk in English?"
I wanted to answer "Of course, I can speak English," but I couldn't do that because uneasiness filled my heart.

Insecurity prevented me from saying, "I can speak English." 

Why do I become the slave of English?

What do I want to be by mastering English?

What's my ideal work in this huge world?

These questions repeat in my head again and again.
It is just a rough draft. haha.
