This effect is there for me as well, even with seemingly milder level of depression than described by others. After 2 years from diagnosis with outpatient therapy and medication, I'm trying to decide to move on from this. When I focus on things I let go of- activities, people, hopes, dreams, it still seems overwhelming, impossible to re-engage as I used to do. The desire is there, but the confidence and energy is not. It seems like another lifetime. I feel at a loss to recapture the momentum of my life; to steer where I want to go, to reclaim my abilities and strengths. I hope this is a temporary stage.
