Big hugs hunny, these first few weeks can be very trying. She will feed less as the weeks go on but right now she needs the comfort as the whole world is scary and you are her safe place. She is also building up your supply so she can grow big and strong. You are doing a wonderful job, well done.

That said a clingy baby at any age can drive a woman close to the edge (I say with experience) so some things that worked for me were:

I didn't co-sleep either, apart from when the baby woke at 5am and it was the only way to get him back to sleep. This way I got most of the night to myself.
a musical swing - gave me a few minutes to have some food
a hot water bottle in the cot before I laid him down (removed of course when he went to bed)
handing the baby to my OH whilst I went for a walk/shower/bath or whatever just to have a few minutes to myself.

In 4 weeks time you will be amazed by how different your baby is and how she acts, but in the meantime don't be afraid to ask for help if you need to get away for even an hour or two. With a clear head you will be so much more prepared to cope.

Good luck
