Like others have said, start with something simple. First books I read were the Harry Potter books and those were fairly easy to read. I'd you dont care about those then there plenty of other books that are very easy to read. Thank you can move slowly towards the classics. Check for word meanings online and keep your own dictionary. Also take it slow. You don't have to read the book in a week. Take a month if you need to. Start reading while taking notes and then mabye read the whole section again so you can enjoy it. Lastly, keep reading. Comments on YouTube, reddit, small articles on stupid thing, whatever it is. Don't stop doing it and soon you'll get good enough to read classics. Remember, it's a journey and not something that you'll achieve in a fortnight.
