Dealing with depression and anxiety is tough. When you’re in the thick of it, everything seems like a trigger, and it’s easy to think things will never get better.

But there’s a clever way to keep track of the highs and lows—and remind yourself that there is a light at the end of the tunnel. Twitter user Kelly Kale (@TheLifeofKale) shared a photo of his sister’s genius solution:

This DIY tracker is very similar to bullet journaling, but instead of keeping tabs on your to-dos and goals, it tracks your mental health. Every box on the grid represents a different day of the year, and the eight colors denote different feelings: red for awesome, blue for happy, yellow for average, brown for tired, purple for depressed, orange for frustrated, pink for stressed, and green for sick.

It looks like Kale’s sister has already had plenty of good days. Here’s hoping there are lots of red and blue squares over the next 11 months.
