Depression

What do you think of when you are alone? When I am alone, my mind quickly takes me thinking to how I am not happy, how I don't feel comfortable at work, how I should not exist. When I am tired, and not had a good nights sleep it is the worst of all. Sometimes, I have played WoW all weekend, or edged to porn all weekend. These days, I don't do that so much, try to take naps over the weekend, try to finish chores.
