nervous about having another baby

I'm currently 11w1d with baby #2, who is also rainbow baby #2. And as happy as I am that we are going to have another baby, I'm also terrified. I'm scared how my daughter will react. If I can love this baby my like daughter. If I can handle having a 2 year old and a new born. Please tell me that I'm not the only person that feels this way. And please give me some reassurance that if you did feel this way that things were good. Great even. It's probably just hormones. I do love this baby. I'm just nervous.
