One of the inviolate rules of nature is what goes up must come down. It is frequently forgotten outside of the context of physics. Sustained success dulls perception of many of the factors one is acutely aware of on the way up. Attempts to backtrack at this point may be futile.

Health
You are under great stress in many aspects of your life and this is having a negative effect on your health. Do not ignore how your feel. If you are feeling unwell seek the help and advise of a health care professional as soon as possible. Do what they tell you, and attempt to follow a healthy lifestyle. If you do otherwise, the result could be dangerous.
