Just as no two people are affected the exact same way by stress anxiety and depression, there is no “one size fits all” treatment. What works for one person might not work for another. The best way to treat stress anxiety or depression is to become as informed as possible about the treatment options. There are many types of talking therapies available. Some types such as Cognitive Behavioural Therapy (CBT) teach practical techniques to reframe negative thinking and change behaviours.
Psychotherapy and counselling on the other hand can help you develop an increased awareness of what you feel, why you feel that way, what your triggers are and how you might change your reaction to them. Psychodynamic therapy (an important component of how I practice) is particularly focused on resolving internal psychological conflicts that are thought to be rooted in childhood. Long-term psychodynamic psychotherapy may be useful if there is a lifelong history and pattern of inadequate ways of coping (maladaptive coping mechanisms) therefore resulting in negative or self-injurious thought patterns and behaviour.
Moreover, I firmly believe that the healing journey or process isn’t a series of invariant, sequential steps set in stone, it may be started from various angles at the same time. As Assagioli has said:
A living human being is not like a building, for which first the foundations must be laid, then the walls erected and, finally, the roof being added.
