I have experienced periods of absolute elation for no apparent reason throughout my 30 days, and the 38 or so before that before I decided to have a few drinks. I have also experienced periods of time in which I am extremely depressed to the point of sobbing my heart out for little to no rational reason. A lot of emotions tend to unearth themselves because they have not been dealt with. You mentioned that you started using again during a time where 'curve balls' were being hurled. You are probably feeling the aftereffects of those curveballs now because you have not allowed yourself to heal properly from them before.
