Satan loves this phase. This is when my mind is ripe for any of his favorite mantras: You can't do this. There's no way. What were you thinking? You'll never meet expectations. You can't even control your own life; how can you be a good mother/wife/Visiting teacher/friend/volunteer/(insert role here)? You are incapable. You are failing.
The weird thing is how easy it is to forget who Satan really is. He is a liar. Pure and simple. An every-thing-he-says-is-not-the-way-things-REALLY-are liar.
