My English isn't so bad?

I'm not confident of my English at all. That makes my English conversation worse.
But, I recently started feeling that my English is quite well, given that I've never lived abroad. Most of Japanese people who can speak English well have lived in an English-speaking country, or even grew up there.
But I need to be able to speak English like them, so although I started feeling that way, the fact that my English is still not enough hasn't changed.
I just gave myself a small praise about my English for the first time.
