Baby won’t sleep

My daughter is 9 months and still wakes every 2 hours if not sooner and wants to nurse. During the day if I try to put her down for a nap awake she will cry and cry and cry. Anytime I put her down she wakes up and crysssssss. I know it doesn’t help but for now I just let her sleep on my lap or lay down with her so I can sleep too. Up until about 4/5 months she was fine and was sleeping through the night. She goes to bed at 7/730pm-630/7am and wakes usually 5/6 times. I repeat nothing will put her back to sleep other than nursing her. I’ve tried crib in her room, play pen in our room, co sleeping, white noise, giving her a soother, putting her down earlier/later.I’m exhausted and just so frustrated. My bf can’t put her to bed because she just wants to be nursed to sleep. Let’s not get started on how i have zero me time/get nothing done around the house. H e l p
