It's true

What perhaps most needs to be emphasized here is that ruminative thinking is evaluative thinking. Whether it’s depression or anxiety, self-absorbed people compare themselves unfavorably to others, believing their problems are unique or at least less resolvable than others’. Stuck in a seemingly endless feedback loop, they torture themselves with discouraged, worrisome thoughts. Anguishing over their problems - and so, making them appear even worse - they experience great difficulty coming up with tenable ways of disentangling themselves from this largely self-constructed morass.

What’s also common in those with depression and anxiety is that their aversive thoughts are distorted or exaggerated. And the reason that therapy can be so helpful for them is that they need someone whose authority they respect to introduce them to a fresh, more hopeful outlook that directly counters their stagnant, self-thwarting one. Absent some kind of external intervention, the unfortunate result of all their obsessing is, as Watkins puts it, “increased sadness, distress, and anxiety, reduced motivation, insomnia, and increased tiredness, self-criticism, pessimism and hopelessness.”
