Sleep Training Breastfed 9 month old?

I am desperate and would truly appreciate any advice. My 9month old has always nursed to fall asleep and he constantly wakes up about every hour all night long. I haven’t had more a few hours sleep at a time in over 9 months 😴 ☠️ I feel like I’m falling apart. To top it off he is now biting me while nursing and I don’t know how to get him to stop. I have a 3 year old as well who

Also nursed to sleep as a baby but she was a better sleeper and not a biter.

He will not even let me rock him to sleep he just screams. I try putting him into his crib sleepy and he immediately freaks out. If I try to let him cry in the crib for a bit and then comfort him he gets even more upset when I hold him and tries to thrash himself out of my arms 😭😭😭 I’m really losing it here I can’t stand to let him cry for long it breaks my heart

Also I can’t pump and store milk I have high lipase in my milk and he will not drink it after a it’s been stored in the freezer so I can’t have hubby give him a bottle
