Why ?

I want what everyone has, I want my rainbow baby, I want to be a mother! Why can't I ? There are females out here that God bless them with kids and they are horrible mothers but I was going to be a good mother and I can't after my miscarriage it has been so hard to conceive . . 😥 I don't understand why people say everything happens for a reason well what reason is there for me to have a miscarriage when I was going to be the best mom to my child ! Life isn't fair ! 😪
