When you get a bunch of discouragement all at once, you can look at it as good. It very likely means that the enemy knows God is getting ready to do something really great so he wants to get your eyes off God. He wants to get you bummed out and in a bad place. He wants to take the blessing God has for you away before it gets to you. The enemy hates God's kids because he hates God. He knows if he can mess with God's kids he is in a way messing with God.
Don't let discouragement, criticism, jabs from others get to your heart. Those things aren't from God no matter who they are.
