I need an advice

personally learned english by watching YouTube and shows in English when I was a kid so I just naturally learned it
Try watching videos in English with ur captions translated to ur language if u can't understand and constantly look up what certain words mean if u don't understand them , u can ask gemini to simplify complex paragraphs to simple English and u can learn to read them urself
This tbh, I haven't learned any English for like 10 years probably, I started to watch English YT content a few years ago and it def helped me a lot, watching movies or anime or whatever and looking up stuff you don't know might be a great help, and as @The WifeThe Wife is verified member. mentioned I can recommend Babble personally too, if you want to save money just buy it with a Brazil VPN cuz they have the cheapest price there AFAIK
