Since I have come to man's estate I no longer suffer from anguish that has no known cause, doubly hard to endure because mysterious, I no longer feel as if my feet are treading unfathomable depths in search of a firm bottom.

I no longer suffer without knowing why.

No, such emotions belonged peculiarly to my childhood, and this book could properly bear the title (a dangerous one I well know): "A Journal of my extreme and inexplicable sorrows, and some of the boyish pranks by which I diverted my mind from them.".
