This hopeless vision of the future is based on a general global perception that their problems are huge, innumerable, and insolvable. Without plans for changing, they have no hope and no motivation. They feel like victims, not masters of the situation. That is unreasonable. They can change.
Depressed people seem to reason poorly in several other ways.
They see nothing illogical about giving credit to luck, other people, God, fate, etc. for the good things and blaming themselves for the bad things in their lives. Others see only the bad. There is still more wrong with the depressed person's thinking processes. Depressed people must learn to think differently. We need to understand why some depressed people are such rigid and poor thinkers.
