When I’m stuck in negativity, I know “this too shall pass,” is objectively true. But if I harangue myself with that phrase when it doesn’t resonate, I just prolong my negativity.
So I accept whatever thought arises naturally, even if it’s false. It could be “this will last forever,” “this is hopeless,” etc. I don’t agree with it and I don’t amplify it with conscious thought (justifying or rationalizing why it’s endless or hopeless), but I let that irrational, emotional part of me be heard and felt within my own mind. No one else needs to know what I’m thinking, but I like to respect/acknowledge that illogical part of me, so that it can have its say, we can politely agree to disagree, then both go our separate ways. It is a piece of me, after all, and I’d rather not fight myself while I’m going about my day.
