12 weeks tomorrow and still doesn't feel real...

Candice • I have an amazing 4yr old daughter, who was a rainbow baby! We are now expecting a rainbow baby, another princess!
After trying for 2 years and a total of 5 miscarriages, the longest one going to 10 weeks. I am finally pregnant again! I will be 12 weeks tomorrow and baby has a strong heart beat of 175 at 11 weeks! But I still can not get excited, I feel so guilty because I have a beautiful baby inside me that I love but I'm so scared to be let down again! How do I move past this? None of my family or friends TRULY understand because they have never been the ones in my shoes. Does it just take time? Any advice or prayers are helpful! Thank you!
