J.S.
This is going to sound mean..... I had the same type of issue and it was the only thing that worked.
Put her in her room at say 9pm (or what ever bed time you pick) and do not go in until morning. Let her cry. She is safe she doesn't need to be changed, she doesn't need to be fed, she needs to sleep and put herself back to sleep. It took 3 nights and I had to sleep on the other side of the house. My pediatrician said this was ok and Sophie wouldn't be damaged and she wasn't. You can get safety things for the door knob so she can not get out of her room. So basically say goodnight see you in the morning and stick to it.
Good Luck
