Fear and resentment
From In the Realm of Hungry Ghosts, on p. 364 of my copy:
The dominant emotions suffusing all addictive behavior are fear and resentment – an inseparable vaudeville team of unhappiness.
One prompts and sets up the other: fear of the way things are and resentment that they are that way; fear of life and resentment that life is as difficult as it is; fear of unpleasant mind-states and resentment that unpleasant moods and thoughts persist; fear that we'll never feel all right and resentment that we cannot feel the way we want to; fear of the present & the future and resentment that we cannot control destiny.
