Tired and unmotivated has been the face of many of my depressions.
I think it sucked even more because I wasn't actively feeling depressed, just checked out of life, and didn't know how to check back in or where to get the energy to do so.
My point is, don't be so quick to dismiss what you're experiencing, IME, it causes me to get stuck there.
As they say, nothing changes if nothing changes.
