If you do nothing, expect nothing.
If you attempt to work on your personal problems, be they psychological, physical, financial, whatever, you are more likely to make a change in your life than just accepting that this is your life.
Especially, when the outcome is exact opposite than intended after many, many months of hard work on yourself.
I've also struggled with depression, hence the "sitting on your ass", wallowed for many years and just tread water. Execute on intent—do something—carpe diem—make a change—you can always make another—just don't accept your life as-is if you're unhappy with it.
Also, as you say, it is very important to not accept bad state -- this is so important I can't stress it enough. Even more, because of how some generic people mindset can easily get you into "learned helplessness" state.
If you’re going through hell, keep going!
Unless you already know it's the right train, in which case you probably already have a ticket and are standing on the platform with your baggage.
Donkeys may be slow but they’ll get you there eventually.
No need to immediately jump on a fast train when things will eventually turn around…or not.
