Burntout stress

Yesterday, it was the hardest day for me. Almost 24 hr i didnt manage to get sleep due to my daughter , 6 month old was awake from 7pm to 7am in the morning. Until my husband is back from night shify. Thruout that 12 hr she sleep 20min and then keep crying and crying. I was going crazy. I dont know why is she like this. I had a toddler to handle too. Any moms going through a period that baby cry and cant be console or comfort?
