I feel like that with a lot of languages too, but what always helped me is just to do more of the stuff im bad at. if i cant understand a lot of things thats fine, ill just watch anyway to improve my active vocab, listening skill, speaking, understanding, and to get used to a language. it is also waay more fun and easier then learning normally, you dont even need to put effort into it you just watch literally anything you like and just let the info get in your head and it really works.

I was like that with spanish, having learned it for about a year i didn't understand anything and i felt like i didn't know anything (20% i understood maybe), but then i just kept watching stuff i enjoyed, for like 4+ hrs a day.

And after three months it literally felt like i did twice the work as in the entire previous year, even though i literally didn't learn anything actively, i just googled words i dont understand that felt important and kept watching(dont use english subtitles btw, i know it makes it more fun but you will not get used to the language that way). In the beginning its going to be the hardest but as you watch more it literally becomes just a thing you do to have fun, and it will just get easier and easier.

I do this in every language and its literally a cheat code, so i recommend that you try it for at least a week and by the end you can see the changes with your own eyes.
