Dear J.-
Your beautiful daughter is completely normal, and has bonded with you. She will not be able to happily go down without body contact with you for some time.
I did find that two double mattresses were helpful. Mom is the person in the middle, and moves back and forth between them. I remember being so exhausted that I could fall asleep while I was sitting up at the table eating- that went on through my son's first nine months. Full nights were unavailable until he was a year and a half. Bed sharing went on after that. You are very important to your child's happiness and feelings of security. :-)
Have hope and faith- this, too, shall end- and you will miss it! Hope it helps - S.
