I bet you are exhausted. Hang in there--there is sleep to be had!
I feel like your DD is trying to tell you something by all of the crying. I see why pp recommended the ferber method; it does work and has worked for a lot of families! But essentially you have already reported doing a form of CIO if you put her in her crib--she cries--- you wait--- go in and check wash, rinse, and repeat still with zero sleep progress. Based off of that, I do not think a CIO method would be affective for your LO.
If I were you I would try something completely different. Can she sleep with you? I feel like at this point you both need to do whatever it takes to get sleep! What is your bedtime routine? What is her environment like when put to bed? What is your energy like when putting her to bed?
I wish I had a definitive answer for you! What works for my son :
A consistent and predictable bedtime routine (bathies, jammies, books and cuddles, sometimes we will do lullaby songs with a read a long book, prayers, and na-nights) Daddy takes him to bed gives him the same baby blanket and tells him he is our world, and the world we love. Turns on his fan and night light and shuts the door.
A space heater that is programmed to keep the temp in his room 74 degrees
A fan for white noise
If he does cry-- we go to him! At this stage in the game I can differentiate between a serious I need you cry or... I am just trying to gain proximity cry! If it is a serious cry...that is when we go get him!
