Found out she was pregnant 😡

My boyfriend didn't want to tell me his buddy from the Navy girlfriend was pregnant. They've been together for a year and we've been trying for months. Am I crazy for being envious and mad that everyone else but me is getting pregnant? His sister is pregnant.. (She cheated on her husband and got pregnant), his sister in law is pregnant. I feel like God blesses everyone but us. I know it's in his hands but I'm just so upset. I cry all the time and I'm super depressed. I feel broken.
