Sooo Scared & Excited !!

After my miscarriage with my daughter, and I found out I was pregnant with this one I'm just so scared!! I am 10 weeks now and as the time approaches in my pregnancy when I lost my little angel, I get more and more worried! I'm so excited though at the same time. I just don't know what to do with myself anymore. I feel like I shouldn't get myself attached, but I can't help it the second I found out I was pregnant with all my babies I'm always attached immediately. What should I do I feel like this one is going to happen, but at the same time I'm scared!
