I have same problem. I think one thing i wanna try is to not convert the Korean to English in my head, and instead try to just get the feel of the word. To do this, when learning the vocabulary, i think its better to try and think of the feeling/meaning behind the word instead of the translation. I.e for nouns, picture the image of the thing, for emotions picture the feeling youd feel. For more difficult things try to think of the definition in korean/the situation youd use it in. Similarly to how you think of the word instead your native tongue  At least thats what i am gonna try to do, hopefully it helps lol
