Am I a bad mom because of this?

I have a two year old daughter that I absolutely love more than anything, and I’m due to have my second daughter in July. I love this baby girl, I love feeling her kick and move, I love seeing her on the ultrasound and I can’t wait to meet her... But today, I was hit with a fear I can’t shake. I’m scared that when she gets here, I won’t love her as much as my first.. I’ll follow this by saying, I never had siblings, I’m an only child myself and wasn’t raised in a good home, so maybe that has screwed with my mind on it. For some reason I really am having a hard time seeing how a love that great can be put towards two different people. I know I probably sound horrible, I feel so guilty for it even crossing my mind, but for some reason it did and I can’t shake it. I’m afraid about splitting the love and attention in a way neither of my daughters will feel like I don’t love them or care about them the same.. I hope this makes sense :(
