Psychological counseling, this is an unexpected question or something you can't understand. Then go to a counselor and tell him that you are confused, or that you feel that you need counseling. Then, the counselor will give you a revelation, or help you analyze what caused it, and so on. This is just an introduction.
Psychotherapy, that's another matter. This charge is relatively high, and there must be periodicity. In other words, how many days does a course of treatment take? If you do this treatment, you will also tell your doubts or what symptoms you have. Then, he will make a treatment plan for you, what to do every day or when to sleep, and so on. He won't give you this plan and then follow it and bid for the hospital.
Mental health education, this is what Christine said. Many people can take classes. This is a prevention lecture, which gives tips and guidance on mental health from the aspects of society, work and life.
