When you're feeling all over the place, going into nature brings a sense of simplicity, allowing space and time for clarity. Without societal and materialistic pressures, you'll better understand what brings you balance, joy, and calm--- as well as what causes you pain, shakiness, and fear. It all helps you to know yourself, and the world around you, better.
Just you, fresh air, nature, and time to gather your thoughts.
Clarity will certainly come.
