Try to say what you want to say and if you don't have the words or grammar to say it, then use Google Translate or ChatGPT to help. Once you get your corrections, you will figure out precisely where your problems are and you will learn how a native speaker would express the same ideas. This is the best kind of help you could ask for and it's based on your own writing and thoughts so it's easier to remember than anything you could find in a grammar book.
