Thinking

Perhaps we had been leaning too heavily on Reason that last mile and we did not like to lose our support. (Big Book)
... then shall vanish all vain imaginings, all evil disturbances and superfluous cares ... (One Day At A Time In Al-Anon)
authority ... has to be frequently used instead of reasoning itself as a method of getting conclusions. For example, few of us have followed the reasoning on which even ten per cent of the truths we believe are based. We accept them on authority from the experts and are wise to do so, for, though we are thereby sometimes deceived, yet we should have to live like savages if we did not. (C. S. Lewis)
This thought about _______ does not mean anything. It is like the things I see in this room [on this street, and so on]. (A Course In Miracles)
Sandy B: 'I'm unhappy.' Sandy B's sponsor: 'What if you're wrong?'

We loved to have people call us precocious. We used our education to blow ourselves up into prideful balloons, though we were careful to hide this from others. Secretly, we felt we could float above the rest of the folks on our brainpower alone. ... Since we were brighter than most folks (so we thought), the spoils of victory would be ours for the thinking. The god of intellect displaced the God of our fathers. But again John Barleycorn had other ideas. We who had won so handsomely in a walk turned into all-time losers. (Twelve Steps and Twelve Traditions)

To be unhappy is to have drawn a conclusion. A depressed or anxious emotional state is the result of a thousand conclusions. Conclusions are like termites.

Fumigate.

Who am I to think and understand? What do I really know? Why am I relying on myself? What results am I getting?

Let go absolutely. Stop scrolling my mind and wake up.
