I might feel like you when I learned English. As your friend said above my writing, You have to read books written in Hangul loudly and write something down on your note and ask your Korean friends including me correct your writing. Don't worry!! Let's go step by step!!

try to read about your favorite subjects written in hangul and if you like some sentences or short paragraphs , write it down
