How to Speak English in English

Don't ask for error correction in the moment. Don't try to speak a lot bef you're ready, speak when you feel ready. It's perfectly normal to make a lot of mistakes when you speak. Most english learners underestimate how many mistakes they make while speaking. You can also talk to a native speaker if you have a lower level but it would be better if person also spoke your language as well. But don't try to force your sentences out if you just don't feel comfortable yet. Just keep on practising. Keep on listening. Eventually you'll start to understand the other person very well and you'll feel more comfortable to start speaking.
