My friend talks about the Shadow. It is the coming of depression. The signs are often apparent, from a fair way out. There is advance notice, a telegraphing of intentions, that things are up for a change. There is the twilight, and the dimming, before the Shadow truly arrives.
Me, I can spot the signs from a week out. Things that don’t normally upset me, do, and things I normally don’t enjoy, or pass over quickly, suddenly offer new attractions. Depression is a destablising force, something that whacks your character out of balance. It can be the impetus for great change, but it’s also about losing who you are, your true identity.
