Can relate. I don't know how, or why, or what I did to get to the other end, but one day I woke up, and it was gone. Years of nearly crippling depression, ruined friendships, hardships at work, nights of 'considering', all finished in an instant. It was absolutely bizarre and wonderful and concerning at the same time.

Woke up and thought "alright this is stupid, I need to get stuff done" and as though it were magically manifesting out of thin air I had a normal train of thought, my emotions were mostly in check, and I had motivation that I hadn't felt in years.

Almost like cracking a knuckle, but in my own brain. GP's comment resonates very hard.
