Hello & Welcome, Jamby. Unfortunately depression frequently entails severe impairment of one's ability to summon motivation, plan and feel excitement.
But you already understand that too well...
Have you discussed your need for some kind of real, touchable plan with your therapist? Does your therapist or prescribing doctor have a formal "treatment plan" for you?
