I've had the same many times. You are not a failure. Not all daycare kids mesh well with our personalities and daycare styles and it doesn't mean we are failures. Some mold well with us and others don't. I had one that I kept. He took two mths to adjust. The only reason I kept goin was that I saw little bits of improvement. Ate and napped well. Stopped crying if I comforted him, etc. I had another one that I let go after two wks. He cried all day. Didn't eat and didn't nap. Didn't even want me to carry him. Was so not working so off he went. So ask yourself. Is she showing bits of improvement? Is she napping well and eating well? Or does she just cry all day? U have to think about yourself and the other kids and do what is best for everyone. Chances are she'll adjust better in a different daycare maybe one that is lower ratio and can carry her all day.
