Ask HN: Self-doubt, inferiority complex is killing me. How do I fix that?

I'm a CS student. Recently I have been battling with self-doubt a lot. I'm super self-conscious when I'm coding as well as when I'm speaking English--my 3rd language. As a result, I avoid trying to solve hard coding problems. I freak out when I have to pair program with someone or when someone else is reviewing my code. And I tend to make a lot of syntax errors. I also tend to rely on documentation a lot. Furthermore, I tend to make a lot of stupid mistakes when I'm speaking English even though I have been living and attending college in an English-speaking country for the past three years.

Could you guys please give me some advices on how to deal with that issue? Thanks lot!
