Kinda angry at God

Before anyone says anything this is mostly a vent post. But im kinda angry with God. I have a beautiful 2 month old little girl who i adore with my whole heart. Wouldnt change her for anything cant picture my life without her. But by getting pregnant with a girl my best friend had to deal with her loss of a daughter which took a while and her boyfriend is struggling with her. My fiancees family is notoriously known for having boys. This is one of the first girls. Did he do this to help them get over what they had been avoiding or why would he make it so to where the closet people in my life that I love like family are having to work so hard at being ok with my daughter? Is she destined to do something amazing? Or is she as my best friend says a gift from her daughter telling her that its ok for her to love another girl? Postpartum depression isnt helping me much.
