Get this in your mindset. Stop believing the 'thoughts' placed in your mind by the enemy no matter who or how they may come to you. Create positive, miraculous, encouraging thoughts of your own. The Word (Jesus) said that David 'encouraged' himself. You can too. You are allowed to. Get ta gettin'!
1 Samuel 30:6
6 And David was greatly distressed; for the people spake of stoning him, because the soul of all the people was grieved, every man for his sons and for his daughters: but David encouraged himself in the Lord his God.
