Yes, but...
Sisyphus is a fictional mythical character used as a metaphor.

Even your quote from Camus seems to argue in favor of CONTINUING the struggle of one's existence.

"Sisyphus teaches the higher fidelity that negates the gods and raises rocks. He too concludes that all is well. This universe henceforth without a master seems to him neither sterile nor futile. Each atom of that stone, each mineral flake of that night filled mountain, in itself forms a world. The struggle itself toward the heights is enough to fill a man's heart. One must imagine Sisyphus happy."

Depression sufferers are not mythical or metaphorical, they're real people with a real condition that can be treated in a variety of ways. It may seem like a Sisyphean struggle to deal with at times, but given the time and patience to find the right combination of professionals, treatment and/or medication, it can be often be brought under control successfully and allow those who have it to get back to a life they can enjoy.

So, I'm not sure I understand exactly what your position is or your disagreement with me is, lengthy though the Camus quote was, so if you can spell it out more clearly (and succinctly), maybe we can discuss it further.

If it's going to be one of those free will / tragic poet / self-destruction as a rational choice / bullshit rationalizations for not getting the help that's readily available because some prefer dramatic failure to success involving tedium and hard work, you can skip it, as that's childish and shallow.

(Seriously though, Camus? The Richard Bach of the black turtleneck set?)
