Psychotherapy is a process by which you examine your thoughts, feelings, actions, and relationships. With the assistance of a skilled professional, you will evaluate where problems exist, or where changes are likely to improve your life satisfaction and overall psychological adjustment. You can then learn how to make the necessary changes that needed to achieve a better life adjustment and satisfaction.
The terms counseling and psychotherapy are interchangeable because they describe the same process and have similar goals. Counseling has its roots in personal development and life adjustment theory, while psychotherapy has its roots in a more medically oriented model of treating a mental disease process. Health insurance companies use a medical disease model, so insurance reimbursement is for "psychotherapy", not "counseling". The distinction is unimportant in applying the process to life management problems, although sometimes, lesser trained counselors will use the term "counseling" to avoid being accused of providing treatment services they are not qualified to provide.
