This was a very moving and thought-provoking post, and the illustrations truly capture the feeling of confinement in hopelessness. As someone who struggled with life-debilitating depression for 10 years, I wanted to add my perspective here, which is that recovery _is_ possible. I, too, used to hold onto "tomorrow" or "someday" as a beacon of hope for renewal and wellness, always in the unreachable future. 

I agree most especially with this point you made: "You must be willing to look at your origins to discover what might be holding you back." For me, I had to learn how to tread the line between ruminating unhealthily and actually gaining helpful insight from introspection that was rooted in reality and could be acted on. 

Essentially, what helped me the most in overcoming my depression was learning how to accept reality for exactly what it is. A lot of that involved learning to love my so-called "shadow" described by Carl Jung, and by accepting my own shortcomings and the failures of other individuals and institutions. I was then able to recognize the limits of my own effectuality in the world and renounce the unnecessary guilt of impotence—or rather a lack of omnipotence—that had plagued me for years. I gave up the burden of trying to "help" others or change things beyond my control. By reaching this realization, I was able to take control of my own life (and mind) to the degree I understood myself to have power over it. 

I never believed it would be possible to live completely free from depression for nearly two years and counting, especially after treading thin ice for a decade, but now I see that it is possible to make a full recovery, and ultimately happiness is my choice which stems from how I look at the world and my place here. 

Depression is immeasurably tortuous and I wish you and anyone else who suffers from this affliction the best. Thank you so much for sharing this post.
