When I make mistakes in my work

Recently, I have made many mistake in my daily work. I think the main reason is that I am too careless, and I am nervous when I am working. Most of the mistakes are typos, such as typing the wrong email address. Those mistakes really annoyed my team leader. I want to do better but I become even more nervous. And the situation is becoming worse, God please help me!. I am crazy!

I want some better way to do my work.

[Your problem is nervousness, but telling someone not to be nervous about nervousness always sounds a little funny.  When you get too exited, relax and take three deep breaths.]
