Baby won’t sleep, help

My baby boy is just over two weeks old and his dad and I haven’t slept more than 45 mins at once since he was born. He is exclusively breastfed & nursing only. At night he will only sleep 20-45 mins max before waking up and screaming with gas pains and needing to feed, sometimes it’s hours before he will go back down for his next 20 minute nap and we feel like we’re losing our minds because we can’t get one single night of rest. We have tried back & tummy massages, bicycle kicks, burping, constant gas drops, fancy bassinets, different sleep positions, lots of pediatrician visits. Today we’re testing for a food intolerance. Is there anything else we’re missing? How rare is this because I feel like everyone I know has a baby that sleeps 3 hour sessions. Has anyone done chiropractor for gas?
