Joy

 So your meditation is dry, tedious, no warm fuzzy feelings.  Does this mean that it is worthless?  No.  Why not change the reason you meditate?  Meditate to give God joy!  Your good feelings are not necessary for you or God.  Desire for good feelings, sense of peace and contentment, is really still on the realm of self.  Your prayer is all about you feeling better.  It is a subtle form of selfishness.  Meditation is not about you getting something but rather becoming something.  God is at work in your prayer, so not to worry.  Your life will change for the better, with patience and trust.  If you are in recovery and meditate to feel better, then you have traded in one addiction for another.  That is why you practiced your debilitating addiction, to feel better.  Feelings are optional in recovery.  Selfless service is not.
