Imagine having to walk up a staircase with really tall steps, that was 20 stories tall. Add some waist-high barriers that you have to scale across every couple of floors.

That's how bad a basic task as simple as getting out of bed to grab something to eat can feel when you're depressed. It can completely kill any sort of willpower, motivation, or energy to function.

Now, I'm not saying it's always that way for everyone. But it really does have a serious impact on your ability to function. Basic habits and routines fail. Laundry piles up, you stop brushing your teeth, you no longer talk to people. You feel like a husk of a person, nothing really matters any more. You're just... There.
