Sometimes, it is best to escape everything in your life. You have to schedule time to get out of your own head. Just sit in silence and think of absolutely nothing. Form a bubble around yourself and just exist if only for a moment. Such a retreat is healthy and can help you get through the daily hustle.
You can have your lunch in a park. Go into a church and enjoy a reflective moment. Maybe that coffee shop around the corner has the perfect cup for you and afternoon solitude. Whatever floats your boat, use it to your advantage.
