How might psychological disorders have evolved? Why did they not become extinct?

Psychological disorders have evolved separately from our physical evolution, and largely constitute a response caused by a mismatch of the environment we live in compared to the environment nature meant for us to exist. Evolutionary medicine conceptualizes that the emotions and disorders that currently constitute the majority of mental illness cases were initially developed to assist us to survive in different environments.

For example, overeating that causes obesity stems from the natural desire to store as much energy as possible while times are bountiful, to prepare for the seasons when food is scarce. The constantly changing social and environmental conditions around us are something that natural evolution mechanisms are too slow to follow. Because of that distance, psychological disorders continue to evolve instead of becoming extinct.
