Depression is everyone else seeing the entrance to the magic of Diagon Alley, when all you see is a brick wall.
Depression is looking forward and just seeing blank greyness, even if you could swear you had plans for your future once upon a time.
Depression is looking back on life and only seeing the worst things you have done.
Depression is not being able to focus on a conversation without your mind wandering off to tumble off a cliff.
Depression is dissolving into tears over the most ridiculous little things.
Depression is different for everyone. This is just my experience.
Depression is cruel. It takes away hope, and strength, and so many other things. It leaves emptiness, and guilt, and shame. And the way out is a very long path, one which sometimes seems neverending.
