The more conscious I was of all the good and of all this "beautiful and lofty," the deeper I kept sinking into my mire, and the more capable I was of getting completely stuck in it. But the main feature was that this was all in me not as if by chance, but as if it had to be so. As if it were my most normal condition and in no way a sickness or a blight, so that finally I lost any wish to struggle against this blight. I ended up almost believing (and maybe indeed believing) that this perhaps was my normal condition. But at first, in the beginning, how much torment I endured in this struggle! I did not believe that such things happened to others, and therefore kept it to myself all my life as a secret. I was ashamed (maybe I am ashamed even now); it reached the point with me where I would feel some secret, abnormal, mean little pleasure in returning to my corner on some nasty Petersburg night and being highly conscious of having once again done a nasty thing that day, and again that what had been done could in no way be undone, and I would gnaw, gnaw at myself with my teeth, inwardly, secretly, tear and suck at myself until the bitterness finally turned into some shameful, accursed sweetness, and finally-into a decided, serious pleasure! Yes, a pleasure, a pleasure! I stand upon it. The reason I've begun to speak is that I keep wanting to find out for certain: do other people have such pleasures? I'll explain it to you: the pleasure here lay precisely in the too vivid consciousness of one's own humiliation; in feeling that one had reached the ultimate wall; that, bad as it is, it cannot be otherwise; that there is no way out for you, that you will never change into a different person; that even if you had enough time and enough faith left to change yourself into something different, you probably would not wish to change; and even if you did wish it, you would still not do anything, because in fact there is perhaps nothing to change into.
Fyodor Dostoyevsky
change, regret
