OBVIOUSLY you need sleep too. Advice I've been given that has helped me is this: When your daughter goes to bed, let it be so. When she awakes, check on her, BUT do not make it enjoyable. Make sure she is OK then leave. Do not talk to her, do not comfort her, do nothing. She will cry and probably cry hard, but stand firm.
I've given this advice before to someone else and I know it seems harsh. But, the more boring to her you are, the less she'll look to you in the middle of the night. She'll learn to put herself back to sleep. That's all she's looking for is someone who'll put her to sleep... she's very capable of doing that herself.
This won't help overnight. It may take a week or so, but it does work. Let your thoughts of sleeping all night be your motivation.
Good luck!! I know it's not easy, but you can do it!
PS If you follow through with this, you can ALWAYS give her hugs and kisses and comfort during the day. She'll know you still love her!
