Warning: this is probably going to be long and all over, but I need to vent. +10 to you if you make it to the end

LO is weeks away from her first birthday, and her nightsleep is deteriorating lately. She used to STTN no problems, but for the past 2 weeks she wakes up screaming and crying for me. She is totally normal and happy in the daytime with normal naps, so I don't think there is anything physical going on. (I'm waiting a phone call back from the peds office to see if they think I should bring her in for a check).

Whenever she wakes up and I go in to comfort her, I find her standing in her crib looking towards the door, screaming until I pick her up. She actually gets more upset if she sees me and I don't pick her up. I've tried to lay her back down, pat her back, and calm her down but it makes it so much worse. I've tried letting her cry a little before I go in there and it escalates very quickly, to the point she becomes absolutely hysterical. It seems that she's scared when she wakes up alone.

Once I pick her up to comfort her she does 1 of 3 things. #1. Has a little mini meltdown of thrashing around in my arms, screaming, going back and forth between sitting up and laying back down on me (obviously exhausted) #2 stays awake anywhere from 1-2 hours going back and forth between playing and whining #3 Goes back to sleep with no problems.

This has been going on for 2 weeks now. We have not had a night in over a week where she has went the entire night without a problem. Nothing has changed in her routine. The only thing I can think of that happened before this all started was I was off of work sick for a week, so I was home with her everyday and doing bedtime every night (our moms do bedtime when I'm working).

It doesn't make a difference who puts her to sleep, she still wakes up every night. Usually between 230-3. This morning she was up at 2:30-4:45, again at 5:30-5:50, and then for good at 6:30. I had 3 hours of sleep last night and I work 12 hour shifts (work 3 days/week, and have 4 random days off). Last night was one of the worst nights so far. DH works nights so I do this ALONE all week long. I sleep 5-6 hours a night on a *good* night. It's getting to the point where I have nothing left to give. I don't know what to do. I feel helpless, and honestly I'm starting to feel a little bit hopeless about the whole situation and I feel like it's effecting my mental health. I've tried introducing a lovey, laying her down and rubbing her back to sleep, playing music, giving tylenol, gas drop, teething tabs, and even bringing her to bed with me. Nothing works.

I don't know what else to do. I have no other options. DH used up all of his time off of work to come home and help before. I don't have much time left since I was just off sick for a week. Our families all work full time. Any advice would be appreciated.

Thanks for letting me vent. And if you made it through this whole sob story, big thanks for taking the time to read it.
