When I was at my lowest, in an intensive outpatient program, our homework was to go for a walk, outside in nature, for 20-30 minutes a day. Treat it as a must do. Like if the only thing I did was get outside and walk, that was a successful day. Try it for a few weeks. If you miss a day, just try to get out there the next day. It can help stabilize your mood and gives you time and space to process and develop a sense of direction (literal and metaphorical, of course).
