I usually advise my students to listen to music they like or read interesting articles on the internet or in magazines. Watching series and movies helps a lot. Find the meaning of phrases and words you encounter very often while listening, reading and watching. Try also with speaking and writing.

What I do to improve my English is watch tutorials in English on youtube (it could be arts and crafts, cooking videos, minecraft builds if you're into that kind of thing). This helps a lot because they are describing what they're doing! So you can see what they do, think about how you'd describe it in your own language and hear the equivalent in English! Many people suggest watching English TV shows/shows in your native tongue with English subtitles. I do this as well and find it helps, but I feel like with watching tutorials you are working things out for yourself more which makes you more likely to learn in my opinion!

all of what you are doing will help. The last and best step however, is trying to practice with native speakers or simply with others like yourself, who are learning English. So, now you know what to do. But, what profit is there in giving a solution and having you fetch it out? Therefore, i offer my help to you if you so desire- just contact me (y)

I've been listening to "Slow News in Spanish" -- I imagine the same thing exists for English on youtube. It's helping me get used to listening even if I don't understand everything. You can also try speaking to people here. At least you can tell them to slow down or repeat or explain.

I kind of have the same problem when I'm watching films or videos. In my opinion after analyse what could be the problem, I realized my dificult is the pronunciation, beyond the vocabulary. Sometimes we read in a different way what is saying. I suggest you to look for classes about pronunciation and I particularly use an app called "Lingua.ly" to learn and practice new words (:
