Unfortunately, yes.
Can you suggest me something to read that will be help me understand the better choice of words for certain situations.
You can start by reading english books or watch english dubs of anime, or watch english movies. I know for a fact that Oozora Subaru, a vtuber from Hololive taught herself to speak english by watching western movies and shows.
I can't, because there is no single book that will help you. Even a dictionary won't help as it won't teach you how to use those words appropriately. However, I can advise you to avoid reading a lot of translated stuff, as the quality of translations varies greatly. Write down some words you might use but can easily forget; that's what I do. Also, when you write, you can use a thesaurus for help.
I know words...but the problem is that they don't come to mind while writing. Like yesterday while I was writing, I used a sentence like this,
Ohh.. writing down the words should help i guess .also I didn't know about thesaurus... thnx man.
I am a native English speaker and I sometimes I find words I didn't know existed. Take the word pontificate for example. It means to ponder, or think. I wrote the word down for help, but I also started using in day to day life. For these reasons I am known for my large vocabulary.
My suggestion would be to just read an english novel. Anything is fine. English is my 3rd language but I'm quite good at it. Because in my country one person could at least speak 2-3 language.
Don't worry, just keep on writing, you will get used to it
go to a bookstore, close your eyes, spin three times, and point. whatever you've just pointed at after you open your eyes, buy that book, go home and read it. repeat this each time you finish a book. sooner or later, your vocab will skyrocket.
