Yeah, i saw i young man on the bus once with the saying, "This too shall pass," tattooed in script on the inside of his well-muscled forearm. It really captivated me. What a great thing!
I do sometimes as you, whip myself into a frenzy. But all things pass, and i'm trying not to panic when i feel desperate. Three hours later i am fine, so why suffer even more? I try and just endure, and soon enough i feel okay again. It's a learned skill tho, for sure, and i am a work in progress.
