Nothing gets you out of an emotional funk like the right Scripture.
There is nothing like it.

My Bible reading plan had me in 2 Corinthians yesterday, and the truths from those passages built my faith, corrected wrong thinking, and lifted me emotionally.

It was like finally drinking water after a binge on sodas.  I was feeling bad but did not crave the one thing that would improve my entire system.  So, find a New Testament passage or Psalm, and drink it in.
