Once you've sat with your negative feelings for long enough, doing some mental health hygiene can help to create a more positive mental outlook.

• Start the day by reading something inspiring or meaningful to help you escape doom-scrolling.
• Find a positive statement and stick it where you can see it.
• Also consider gratitude diaries, exercise, expressive writing, a good night's rest and music.
• Consider what your disappointment will look like 50,000 years from now. 
• Imagine yourself from a third-person view.
