Welcome to PsychCentral. I am glad that you have taken the step of joining a social forum group dedicated to fighting mental illness. Having depression does not make you lazy or selfish, as people who don't understand the illness would have you believe. Both people who have okay lives and people who suffer in life can get depression, and it's not your fault because it is an illness. Could it be arranged to have more sessions with your therapist, if you feel it is not enough? Once every two weeks sounds like a lot of time for depression to sink in again to me.
