By this point in your life, I sincerely hope you have been introduced to fun.
When adulting is stressful, it's a great idea to relax and do something that you find enjoyable. When you don't have the option to do what you usually do for fun (due to a new location, the lack of your usual friend group, quarantine due to a global pandemic, etc.) you may feel at a complete loss for how to occupy the time. Stop staring at walls, and take advantage of the moment to try out a new hobby, relaxation technique, or learn about something you've never even heard of.
