Does anybody else feel like a mile is shorter than the length of their doorway?

Once I'm outside of my home I can function, and inside I'm fine, but the act of just going out the door is... I dunno if that's anxiety, but it's unpleasant. I can force myself to do it for tasks or work, but otherwise crossing that threshold is foreboding. 

Is this anxiety? Is this familiar to other folks? Agoraphobia doesn't feel like the right description, but not sure what else you would use to describe this.
