Counselling is a type of talking therapy that allows a person to talk about their problems and feelings in a confidential and dependable environment.
A counsellor is trained to listen with empathy (by putting themselves in your shoes). They can help you deal with any negative thoughts and feelings you have.
Sometimes the term "counselling" is used to refer to talking therapies in general, but counselling is also a type of therapy in its own right.
Other psychological therapies include psychotherapy, cognitive behavioural therapy (CBT), and relationship therapy, which could be between members of a family, a couple, or work colleagues.
