Most psychological treatments mainly deal with conscious thoughts and emotions, but some problems are more deep rooted or the result of subconscious programming.
Hypnotherapy is where the conscious mind is less dominant. It provides the gateway into the deeper subconscious part of the mind. It can aid in many things and can work in conjunction with conventional medical treatments or without.
You will not lose control and there is absolutely no question of being made to do anything against your will.
Hypnotherapy, in short, is the combination of hypnosis with psychotherapy and counselling methods to bring about positive changes in your life.
