It can take a long time for your brain to absorb new ideas right now: you are a bit preoccupied with personal dramas. Make sure that in a work or school setting you are giving yourself enough time to understand what you are reading, studying, or researching. Showing your work to another pair of eyes is a wise idea. They can catch mistakes that you can't and give you good ideas on how to tighten up the loose ends. Take their criticism and listen to their thoughts.
