Halllppppp

My 7 week old is so cranky 😩 she used to sleep through the night from 8pm to 4 am. She was eating 4 oz every 4 hours. Lately she just will NOT sleep. She doesnt take her naps. She will fall asleep but any tiny noise wakes her now and god forbid i try to set her down. If i hold her she will sleep for hours. But the second i set her down shes screaming for me again. I cant cook or clean because i cant put her down. Sometimes a miracle happens and she will fall asleep and stay asleep for about an hour after i set her down. But after that hour shes awake screaming again. She seems to be hungry constantly. Her doctor said she is perfectly healthy and to try gas drops and gripe water but they do nothing for her. I think shes overly tired since she wont sleep anymore and thats why she screams. What do i do? Do i feed her every hour? Do i just have to live this way? I do NOT want to let her cry it out so please don’t suggest that. Shes only 6 weeks 5 days old.
