Stop what you're doing right now and say this:
I declare that JESUS is the Lord of this house and Satan and his cohorts have no power hear. In the name of JESUS I command you to leave.
Then throw your crap in a blender, make yourself a green smoothie, put on some Josh Groban "You are Loved", and check your doorstep because God might just do something like this.
The ONLY way to combat the STUFF in our lives is through prayer. The stuff that gets you down...discouragement, dread, guilt, pain, disappointment...it is all a tool of the enemy to take your focus from God. So get to praying you guys.
Until the next time :-), C
