Your baby is in the "Fourth Trimester" and will need time to adjust to the new lights, sounds and sensations of the world. Plus her own internal sensations – the digestive process is new, powerful, and uncomfortable for many infants. Babies need LOTS of holding/snuggling/cuddling/rocking/jiggling during their first three or four months in the world. They do not arrive with the ability to soothe themselves – that's mama's job until they get a bit older and gradually adapt and learn new routines.
Your daughter may reach a state of even greater neediness over the next few weeks as her system gradually tunes into the sensations around and inside her, but then that gradually declines, and for many babies, is finished by around three months.
How to cope? Most moms get good results from wearing their babies in a sling or wrap that hold the baby close to the body. That gives the baby the sense of security she needs, and leaves your hands free.
I hope you'll get the book The Happiest Baby on the Block, by Dr. Harvey Karp. He'll describe the steps you can take to turn on your baby's "relaxation response" so that she'll feel greater comfort and less sense of anxiety and separation. You can see him demonstrate his magical approach in these and related videos:
