It depresses me when I am helpless. I have someone close and dear to me who suffers from insomnia because of all the noise from the surroundings. Working all night long and going home to such noise is troublesome. It seems endless and there's no escape from. When sleeplessness strikes I cannot do anything as much as I want to help. It sucks and it is depressing. There are other situations that tie you down so you cannot just get up and go and leave and live where you want to live - as far away as possible from the noise. Hanging on and running out of luck.
