How is your life situation? Is there anything that is causing you trouble? Unresolved issues from past? Traumas? This is something to look into.

ANd how is your eating and lifestyle in general? another aspect.

And not to get too intimate... how is your spiritual life? Do you have things in this aspect settled, or still seeking desperatelly? What do you cling to in your hardest times? Is there something that keeps you going? I am not selling one particular faith... "being at peace" is not a religion... it's a crucial thing for life.
