With our fast past lives, and a society that seems to value work above all else, we forget to take time for ourselves. There's lots of research out there pointing to how mindfulness exercises help us to refocus and take a much needed time "out". I've listed an app that's been helpful. Be advised, parts are free, others require a monthly membership. Whether you use this app, or some other tool, taking 5 minutes a day to recharge can make a huge difference. Try to aim for a 5-min a day meditation and see if you notice any changes in sleep or your outlook on things the next day.
