PLEASE, help!!!!

My daughter is 6 months, and she just won’t SHUTUP!!!! Crying all thru the day, night, and wakes up crying. I can’t deal. Nobody helps me with my baby. I am so frustrated. She doesn’t let me sleep right. My schedule is all messed up because of her. I really don’t know what to do, I tried giving her a bottle, try rocking her to sleep, tried a bath, I literally tried everything and she’s still crying!!!!!! I’m losing my mind!!!! I’m so frustrated!!!! I’m so overwhelmed
