((((((( Turquoisesea! )))))))

I don't think you are a failure, but what I think doesn't matter. You feel like a failure, and I acknowledge your feelings.

Your feelings don't exist in a vacuum. A lot has been going on in your life and all that on the background of years of struggling with depression. Depression and low energy go hand-in-hand. As true as that is, is it possible your lack of energy is due to "depression+?" Has your depression diagnosis grabbed all the attention away from other, additional causes of low energy? Have you had a thorough medical check-up recently?

Though I ask this, I do not intend to minimize the power of depression by itself to suck all vitality out of a person!
