For me, the main difficulty is grammar. When I read the rules, everything is clear, but as soon as I start talking or writing, I immediately get confused. It seems that there are too many rules, and they make it difficult to speak freely. How did you cope with learning grammar so that it became familiar and easy?

The most difficult thing in learning a foreign language is to keep your attention and not give up. I often started and quit until I found an easier way. For me, it was the english language application. It does not require long classes, but it gives stable results if you devote at least a few minutes a day.
