Stuck on A2-B1

I am studying B1 now , and I dont really know what I should do to improve, I feel stuck and still on A2 level, I am the kind of person that perform well when knowing what are the steps that I should do , but now , I have nothing in mind, no idea how to improve on speaking , how to start feeling comfortable with the language ..

Etc

And now I heard that lesen is great for improving the level, but I dont know if there are any free resources , or books that works for my level. I tried generating with AI and german guys told me that the texts are so bad and no german speaker would speak or write like that , help me
