Hey all. I'm Polish and have lived in England for the past 12 years, and while I'm still arguably fluent in Polish, I seem to struggle in two things:

Conversations, where I forget words and see myself umm-ing and ahh-ing more than I'd like,

and in writing, where I seem to lack a broad vocabulary and come off as more childish than I'd like due to my young writing age.

Do any of you know any learning resources for people like me, that are medium-high in skill level? My grammar is fine for the most part, it really is just getting more and more comfortable. Of course I'm gonna try and start reading more books and articles in Polish, but I feel like some people on this sub may have some more tricks up their sleeve. Thank you so much!
