I'm not looking for advice - just solidarity!
My DD is a terrible sleeper. From 6 months to about 2 years old she woke every hour. After turning 2 she thankfully started waking only 2-3 times. Except when she's poorly - then it's every half hour.
I feel like unless you've been through this, you just don't understand how unbelievably awful it is. Everyone has been tired, but 'tired' doesn't even begin to cover it. The sleep deprivation is overwhelming. Like... I feel like we should get compensation from the government!
