Growing up my parents Sunday's were a day of rest. We didn't hang out with friends that day, do homework or anything else but spending time together.
Sometimes we'd spent the day baking and decorating cookies, than watch movies together. Other times it was playing board games, hearing bible stories, anything as long as it was relaxing and we spent it as a family.
Growing up I continued those traditions with my own children. I make Sunday's a day to relax, and take care of myself. Sometimes it's grabbing a good book, painting rocks, taking my dog for a walk, watching a movie etc.
Taking time to relax and refocus is so important for your overall health and well being. Maybe you don't have the day because you have a busy life and or other priorities, I get it. Take the time you have to do something for yourself, I'm telling you it will make a difference.
