Has this happened to anyone before ??

My 5 month old cries from the time she wakes up till the time she goes to sleep . Even after a feeding , even after a changing . Can’t get nothing done , holding her she still cries , she won’t watch TV , she won’t play with toys . Doctor says “ babies cry “ when I keep taking her to the doctor , it’s not her milk . I’m really aggravated. It’s been going on since about 5 weeks . All she does it CRYYYYY . I thought maybe by 5 or 6 months it would stop but nope. .
