Keep positive. Be goofy and find new creative ways to have fun. In order to decrease negativity shine some light in your home, listen to music you all enjoy at home together, have dance parties with those you live with, maybe even dress up in costumes to spice it up a little bit. You could bring back family game night, or karaoke. Try out funny voices or act out your favourite characters. Be a leader for positivity and your family and friends will follow right behind you. You can also get those who do not live with you involved in the fun too, video call them so you can all enjoy the fun together.
