Newborn sleep!!

While everyone here is asking if they should let their babies sleep or wake them up for feed , I’m here thinking what I’m doing wrong .My 6 weeks old will never sleep more than 1.5-2hrs at night and more then 30-40 minuets daytime. I know she has gas issues which wakes her up so often but I’ve almost left everything in my diet in fear of causing gas in baby but still the issue is there . We’re constantly using gas drops and gripe water around the clock. I didn’t sleep more than 2 hrs consecutively since baby is born .. any helpful advice 🤕.. ??
