Get a toddler bed or toddler sized mattress and put it in your room beside your bed ~ that way she'll still be close so you both feel more secure! :)
You can start moving the toddler bed farther & farther away from your bed slowly if you want to get her to her own room, but I would not just expect her to leave your nice, safe, warm, comfy arms to be in a big scary bedroom by herself.

Good luck!
