Disappointment in my English level

Recently I had a conversation with native English speakers. It was awful :( I can write on italki because I have time to find words in a dictionary. I can reviewed and change sentences and can verify verb tenses and fix them. But when you speak, you have to do it immediately. You can't change the sentence after you say it. That's why speaking is more difficult than writing. I know that I need to increase my vocabulary and practice grammar more before I try to speak again.

If you keep practicing it will get easier :)
