Psychology is the practice of understanding people and what makes them tick. Psychologists listen to your problems, lift your spirits, and give sound advice. Psychologists are considered professional therapists. They are trained to unravel what is going on in your mind of someone with specific issues.
Typically, sessions are one on one, and there is privacy. A psychotherapist, on the other hand, involves him or herself into the life of a patient so that they can offer them a fresh perspective.
A psychotherapist can be a social worker or someone who specializes in treating people with trauma. However, psychotherapists are not necessarily psychologists. These people are experts at forming relationships with their patients so they may help them.
