If, however, you do end up feeling like that and you can't explain how or why you got that way, there is something (or some things!) you can do:
1) Surround yourself with water.
Water is a fairly emotional element, however it is amazingly clearing and cleansing, and most especially, if it is sea or ocean water. Just being in that beach atmosphere will help remove the negative ions within your energy field, leaving your aura cleansed, renewed, and rejuvenated. If you are unable to get to the beach this weekend then I suggest you simply walk around barefoot in your yard, and then drink plenty of water. The Earth's energy acts as a conduit sending your waves of negative energy way down into the ground. It absorbs it for you so that you don't have to absorb it any longer. And I had mentioned the whole drinking water thing, because even ingesting it will help to flush out negative impurities within your system. Lastly, take a salt bath. Bathing with bath or Epsom salts have been proven to help heal and relax joints and muscles while simultaneously clear your energy.
2) Get a Reiki treatment.
Reiki is energy healing. I, the practitioner, gently place my hands on you and direct positive and healing energy into your aura. It will remove the negative stuff and leave you feeling light and refreshed. Reiki also helps people to gain clarity, and that is something that can get muddled or clouded when feeling "down in the dumps." It's been around for thousands of years and has been proven to be quite effective. If a Reiki treatment is something you are interested in, please don't hesitate to reach out to me.
