I might be at a similar place as you. Although I can't say I'm frustrated. Fatigued. Or just seeing things for how they really are. Maybe there is wisdom in fighting a battle. Going against the tide. But maybe there is also wisdom in seeing things for what they are. And accepting it.
Also, at some point, your whole being -- not just the brain -- wants to feel peace and warmth.
