Comparison is a women's worst enemy.https://twitter.com/tmgrubb123/status/860669545437999104, http://proverbs31.org/ can help you understand that when you compare yourself to someone who looks like he or she has their life together, you are competing with the world and God does not want that!
He wants you to realize that you are special in some way to him! But that does not mean you are his favorite. Here is an example: https://iluvbingjcsbride.blogspot.com/2016/07/christian-perspectives-and-life-of-one.html?m=1.
Acts 10:34-35 NIV
 Then Peter began to speak: “I now realize how true it is that God does not show favoritism  but accepts from every nation the one who fears him and does what is right.
So do you understand now that favoritism and comparison are your worst nightmare? Good!
