5 week old troubles

Me and my fiance are at our wits ends. our 5 week old WILL NOT STOP CRYING. She has an upper lip tie and intakes alot of air while feeding both at the breast and bottle so i know shes having gas troubles. Ive been giving her Mylicon gas drops and it helps a little. I feel like she also has reflux but im at a loss at what to do to help her. Monday she has a dr apt and im going to see if they will revise her lip tie. i also plan to make a chiro apt monday because its been 2 weeks of this now. she cries nonstop, she fights her sleep up to 3-5 hours, cries instantly if shes not being held or moving. Her favorite was the mommaroo and that doesnt even help anymore. she went from being able to be sat down and being the most content good baby to a nightmare.. ive tried eliminating food/dairy from my diet, literally everything. We need some advice.. it seems literally nothing helps and we are very much so sleep deprived and becoming very frustrated
