My crying 1 month old !

My babygirl is 6 weeks and she cries a lot !! Somtimes I would feed her and change her diaper and she would chill for like 10 mins and she would start crying or just whining on and off it’s too the point where sometimes I wouldn’t know what to do just get overwhelmed and start crying cause it’s so stressful.. also at night she has this certain time where she would fight her sleep for like an hour .. someone please give me some advice I get no sleep ! 😩
