Fyodor Dostoyevsky said this quote

You said just now, Don't be so ashamed of yourself, because that's the root of your trouble––with those words, you seem to have reached right into my innermost soul. What I mean is, when I visit people, I always feel that I'm really the lowest of the low, that everybody takes me for a buffoon, so I say to myself, why shouldn't I act the fool, I'm not afraid of what any of you might think, because every single one of you is even worse than me. That's why I'm a buffoon, I'm a buffoon born of shame, great starets, of shame. It's anxiety pure and simple that makes me so unruly.
