Stop smoking. Walk in nature. Cut out caffeine. Ensure a dark, cool, uninterrupted sleep environment. Keep a log before leaving work that lists your major achievements for the day in bullet form so you have the habit of recognizing your work. Don't worry about things you can't control, because it's a waste of your time and energy. If you have to delay the formal marriage registration due to the government's overreaction, so be it. It's irrelevant in the scale of life.
