Here's something to try, I hven't done it so I'm not sure how well it works, but it would be what I would try.
Get a bed and put it next to yours on the floor (toddler bed, or crib mattress), make it as comfortable as you can, so that it feels like mom and dad's bed, put her to sleep how you normally would and once she's asleep, put her into the new bed that is next to you. When she wakes up to feed, nurse her and put her back to sleep, but move her to her bed. Do this until you feel like she's ready for the next step which is no nursing, and just some mommy comfort, and back to bed. Etc. if that works, than slowly move the bed to her room. So maybe she takes naps in her new bed only, than she starts off in the bed when she first goes to sleep, etc. etc. See what works for her, you are the only one who knows your child, so take it slow and make it comforting for her. It might take a few weeks, but it will be worth it in the end.
My first son, slept in my bed and/or in a bed in my room until he was 18 mths old and than we moved and I just told him he slept in his room now and he was fine with it. he is now 2 1/2 and he hasn't been back to my bed or bedroom since. However when my other son was born, there was a transistion period and we sometimes slept with him in his twin bed or layed with him until he fell asleep.
My youngest now 1, slept in the bed with me until about 7 mths when he weaned himself from nursing. I kept him in the room with me and would pull him into bed with me when he woke up, but recently transistioned him to his own room and crib and he's been sleeping for 7 hours straight 4 out of 7 nights a week.
Every child is different....just work with a transistion, rather than cold turkey so that she's comfy.
Good luck

oh and I'm not 100% sure that she might not need something more to eat, my 1 year old still takes a night bottle a few times a week because he's hungry. If it was for comfort, he wouldn't be taking an entire bottle. Sometimes kids need to eat a little more to get thru the night. Maybe try giving her a snack or a glass of milk before bed to help her thru the night.
