"I am now the most miserable man living. If what I feel were equally distributed to the whole human family, there would be not one cheerful face on earth. Whether I shall ever be better, I cannot tell. I awfully forebode I shall not. To remain as I am is impossible. I must die or be better it appears to me."

I don't want to stay depressed; it's just not easy to see the way out. But I will see the way out.
