Up to this point in our depression series we have discussed several conditions that have a depressed mood as a symptom of the condition; this includes premenstrual syndrome (PMS), post-partum blues and depression, normal and prolonged grief, major depression disorder, bipolar disorder and post-traumatic stress disorder. Depending on the condition and severity, medication may be needed to help control symptoms. On the other hand, therapy tends to be beneficial in all these conditions. A therapist can use many types of therapy methods. It can be helpful to know which therapy method is being used in your case or what methods tend to work best for you. In this way, you can come to your session engaged and empowered.
