It sounds like your cat may have learned that if she meows long enough, you will hand-feed her! If you don’t want to be hand-feeding her all the time, you may just want to give her food at night. There is nothing wrong with her eating while you are asleep.
You may also try to resist the urge to hand-feed her and just leave her to eat at night. You may very well see that she starts to eat on her own during the day, too.
