Sleeping in my bed still

My daughter is 2 and she absolutely REFUSES to sleep in her own bed. she’s slept with me in my bed since the start and i know i left it late to start letting her sleep in her own cot, but i still didn’t think it’d be this hard. She cries, screams for hours and she even climbs out of her cot and into my bed😪 It probably doesn’t sound bad, or like i’ve tried everything, but when i say i’m out of options, IM OUT OF OPTIONS😪 Any advice on what to try? It’s been going on since october last year, and most of the time id have to stay up all night and watch her to make sure she doesn’t climb out, but i’m 16 so i still have online school to do and with a screaming, crying child at 4am it gets difficult. When i say she refuses to sleep there, i mean she literally won’t fall asleep. like at all, so around 3:30am i get very annoyed and just take her back to my bed. Help.
