Depression
Being away from co-workers and in the typical work environment can cause depression as well. However, it can be easy to get depressed when you find yourself on social media more often than you should and noticing that there are others who may be having it easier. Either their lockdowns have been lifted whereas the lockdown in your area is nowhere near done yet. Maybe they have something that you wish you had. It is best to limit social media use for 30 minutes a day.
