Looking too hard for meaning, even if you zoom out a little to the context of our solar system is a sure way of getting depressed.
The meaning of life is to experience life, in all that it has to offer.
If you have made your arrangements well, then your job is a part of that. Otherwise, at the very least, it is what you need to do to survive at whatever level of comfort you need - don’t knock it, it’s not a small thing!
From experience, this “dark place” is entirely self-manufactured by your own mind that is not taking instructions from you. Working to address that is he way out.
