"… probably owing to excessive self-consciousness, perhaps as the result of the generally unfortunate cast of my personality, there existed between my thoughts and feelings, and the expression of those feelings and thoughts, a sort of inexplicable, irrational, and utterly insuperable barrier; and whenever I made up my mind to overcome this obstacle by force, to break down this barrier, my gestures, the expression of my face, my whole being, took on an appearance of painful constraint. I not only seemed, I positively became unnatural and affected. I was conscious of this myself, and hastened to shrink back into myself. Then a terrible commotion was set up within me. I analysed myself to the last thread, compared myself with others, recalled the slightest glances, smiles, words of the people to whom I had tried to open myself out, put the worst construction on everything, laughed vindictively at my own pretensions to ‘be like every one else,’—and suddenly, in the midst of my laughter, collapsed utterly into gloom, sank into absurd dejection, and then began again as before—went round and round, in fact, like a squirrel on its wheel. Whole days were spent in this harassing, fruitless exercise."
