Dark to my Core

I feel that same old desperation,
 Creeping up inside.
 The one that makes me
 Want to jump into a hole and hide.
 It's unmistakable,
 Overwhelming sadness hits,
 I'm sinking faster
 Than a ton of bricks.
 It grips hold of me tightly,
 The darkness descends,
 Trapped in this horror,
 When will it end.
 I'm so fucking angry,
 Depression has got me once more.
 I shine on the outside
 But I'm dark to the core.
