If you are still in college, try taking 1 or 2 of the English courses to learn to structure your grammar.
Second, try reading more books in your spare time like time period books that uses a lot of high level synonyms, metaphorical themes and shows a deeper description of emotions and ideas through words. I would recommend Charlotte Bronte’s Jane Eyre, Jane Austin’s Pride and Prejudice etc.
Or, if that is not interesting, reading more books in general helps your mind to learn how to articulate ideas.
