My therapist informed recently that counselling sessions should continue even if you feel healed because the anxiety might return and counselling helps to maintain a direction towards autonomy. Thankfully, I am not suggested for dosing. In order to maintain autonomy, I have not seen my therapist for a month now after meeting her for at least twice every month in last 16 months. I do agree with the author that depression is a natural response to disconnect from the nature. Everyone has a grey side and one must be comfortable to express it. Often lack of expression leads to self-inflicted guilt.
