Modest Ilyich Tchaikovsky said this quote

“ Probably you were not quite well, my little dove, when you wrote to me, for a note of real melancholy pervaded your letter. I recognized in it a nature closely akin to my own. I know the feeling only too well. In my life, too, there are days, hours, weeks, aye, and months, in which everything looks black, when I am tormented by the thought that I am forsaken, that no one cares for me. Indeed, my life is of little worth to anyone. Were I to vanish from the face of the earth to-day, it would be no great loss to Russian music, and would certainly cause no one great unhappiness. In short, I live a selfish bachelor’s life. I work for myself alone, and care only for myself. This is certainly very comfortable, although dull, narrow, and lifeless. But that you, who are indispensable to so many whose happiness you make, that you can give way to depression, is more than I can believe. How can you doubt for a moment the love and esteem of those who surround you? How could it be possible not to love you? No, there is no one in the world more dearly loved than you are. As for me, it would be absurd to speak of my love for you. If I care for anyone, it is for you, for your family, for my brothers and our old Dad. I love you all, not because you are my relations, but because you are the best people in the world. ”
