I need HELP. Now 😔

Our 11 month old will fall asleep at night in his crib but gets in bed with us around 11-12 pm. He STILL nurses 4-5 throughout the night and it’s driving me nuts. I’m not getting any sleep. Any tips on getting him to sleep through the night alone? I know he isn’t hungry because he eats a ton of food at dinner. I think it’s just comfort nursing.

PS. We’ve tried letting him cry it out when he wakes up around midnight but it’s hard because we live in a one bedroom so his crib is in our room. He can see us and screams so loud out of frustration and won’t stop.
