Please help 😵‍💫😵‍💫😵‍💫

It’s 5 am n I’m so tired.!!! For the past week my 2.5 yr old goes to sleep at 8pm which is her bedtime routine and she will sleep until 11pm that’s when she wakes up n it all starts. She will wake up crying hysterically so I lay with her until she goes back to sleep and then she will wake up again 15 mins later crying like if someone hurt her 😐 so I put her on my bed and I go to sleep on the couch so she can sleep alone bc I don’t want her to get used to us sleeping together again and she’s still moving around crying so I put her back on her bed and I’m like ok you’re a big girl stay in ur bed and I go back to bed and she comes crying loud so I put her back again and there she comes 2 mins later crying. I’m honestly drained I literally had a mental breakdown yesterday night because of this. I’m a single mom so I’m having to deal with this by myself. Idk what to do nothings wrong with her like she’s not sick or anything. I put her a new diaper give her a bottle and she still cries. She would sleep through the night until a week ago.

I do have a white noise machine it worked before b it not anymore this past week :(

I let her sleep with me but she just moves around alot and won’t go to sleep just keeps on crying :/
