I know that "I think I'm going to have a heart attack" sounds hyperbolic, but I really think I may have a heart attack over this quote.
Let that evil thought go .. turn it and your upset over to God NOW!! I mean it ... God's work can't be done when we allow satan's minions to penetrate our brains like an insect .. PRAY PRAY PRAY. Replace the negative feeling with other pleasurable visions and take control of your mind and release it. You AND God can do it, if you focus on His mercy and beautiful handiwork here on earth.
