Burn Out?

Anyone ever suffer from spiritual ministry burnout?  There comes a point when all of your spiritual fruit gets plucked and a respite is needed to just be alone and do nothing.  No obligations, no necessities, no plans...no nothing.  Living and working at a ministry is rough on one's mind, will, and emotions as well as one's spirit.  A rejuvenation period is mandatory at least once every 6 months or the privilege of serving the Lord Jesus comes to seem like a chore.  Especially when it seems like everyone is getting helped but you.  It's not necessarily akin to the gall of bitterness but more along the lines of "Can't I get a breath here?"  I thank the Lord for choosing me to serve Him and Jesus is the reason for every season but even He went to the mountain occasionally.
