Do you experience any form of physical pain? Emotional and mental stress can sometimes manifest into physical ones (usually pain around the top back area or the neck, hence the expression pain-in-the-neck).

Perhaps it's a good time to explore journalling or meditation, or maybe a change of environment. What happens on the inside reflects on the outside, and now that you're aware of the "off" energy, you can make a conscious effort to change it.

Hope you feel better soon. :)
