13 month old driving me crazy, please help!

My 13 month old still nurses to sleep. For her nap and bed. She also sleeps with me. Has since birth practically since she REFUSES to sleep anywhere else. CIO won't work with her as if she cries longer than 5 minutes she's vomiting. I've tried nightweanint for an entire week and it's not working as she'll cry/scream till she gets the boob. She has been this way since she was born. She didn't even want to be in the hospital baby bed thing. She HAD to be held, even the nurses commented on her demandingness 🙄 she also still nurses every hour. From 5 minutes to 30 minutes. She won't play by herself not even for a moment. We babywear A LOT because she refuses to not be in someone's arms. I'm getting extremely touched out, and I'm getting overwhelmed by her constant need of me. I see all these 12 month olds who are capable of playing alone even for 5 minutes. 😞
