From I'll Be Honest. Thought this was encouraging.

"If God has withdrawn His presence from you then get alone with Him and
plead with Him to restore the joy of your salvation. If there is
anything "in between" deal with it and get it out of the way.
What ever you do, don't build your own fires with the energy of
the flesh. Don't walk in a flesh-created enthusiasm that
evaporates like dew the next morning."
