Keeping busy during quarantine is difficult, you can try doing some manual activity, cooking, reading, or any other activity that helps you de-stress and not notice the passage of time, here are some ideas:
-prepare your favorite dessert
-read a book that someone gives you as a gift or recommended
-see an old movie and analyze its content
-grow a plant
If you do not know what else you can do, write your thoughts, and I will gladly read them and make a comment.
Have a nice day
