It's perfectly normal to be upset with God. Do not allow anyone to shun you for feeling as though you are wrong for feeling how you feel. While we are spiritual beings, we are still human beings going through human experiences so as a human being, there will be moments when you get upset with the creator. I get upset with my parents sometime, does that make me wrong? Do I not love them because they are my parents? No, I'm human and as humans we are granted emotions BY GOD who grants us grace
