Clingy 7 month old rant

Sorry as the title suggests I just need to rant. My baby currently required me 24/7 again, probably worse then when she was a newborn. The last 3 nights she’s been awake literally all night needing feeding, comforting etc. I can’t seem to get her to fall asleep on her own, she’ll have 2 hours after bedtime when she’s asleep but then the rest of the night she’s crying and whinging. I’m exhausted and so emotional. She can’t sit unaided yet, no interest in doing anything other than crying at the moment. I’m trying my absolute best but the sleep deprivation is kicking in and she also requires me to pace to get her to nap, I’m one very stressed mother right now :( please can anyone suggest ways to get her to sleep on her own and tell me I’m not alone.
