How many kids do you have?

I find myself thinking that I'm not going to have enough love for both of my kids, I have a two year old and I am pregnant, I'm so used to it always being just her and mommy and I know it sounds selfish because my husband and I really wanted a baby but I feel like it is too soon (not that I can or will do anything about it now) maybe it's just the hormones, idk but I don't think I'm ready to have another baby. I just need so friendly advice on how to handle the transition for both her and I. I know it sounds bad and I know I will love the new baby but I don't feel like I can love it as much as I love her? I sound crazy don't I!? :(
