Ensuring that you take time for grounding activities such as meditation is essential to relieving some of the stress induced aches. If that is not within your comfort zone then try juggling. Yes, I said juggling. It offers the same mindfulness that meditation does, once you get past the agony of learning, that is. Another great grounding practice is daily self-massage with sesame oil in the morning 20 minutes before a warm shower. In addition, walking a few minutes a day in nature will help restore balance and provide a feeling of well being. Taking supplements such as Stress Care from Himalaya a few days before you get really busy will help and drinking warm milk before bed will enhance your sleep allowing for greater concentration and patience during the day.
We all have "one of those weeks" but the important thing to remember is that, like everything else on earth, it is a temporary state. You will get through it, and so will I.
