Sleep regression

Anyone really struggling with sleep right now? Between learning to crawl, teething, learning to pull herself up.... my little one is just not sleeping. Last night she went to bed at 7 PM, and decided that wake up time today was 5 AM. She had 7middle of the night wake ups! I feel like I'm going to die. Her sleep is worse now than it was when she was a newborn! We've tried everything – sleep training, cosleeping, bed sharing. Nothing is seeming to work. I am so tired!
