Is her toenail falling off ?!

My daughter has had a yellowish color to her left toe nail. It didn’t seem to bother her so we applied neosporin regularly. I sent pictures to her doctor to let her know what was happening and if there was anything we could do. We got a message back from a nurse letting us know if there are any signs of discomfort to give them a call. I THOUGHT it was getting better bc the yellow had gone away but now it looks like this. I’m freaking out!! I feel like such a terrible mother for not bringing her in to get it checked out 😓😞 I’m worried it’s going to fall off and her doctor is out of office until the 30th. I usually cut her nails when she’s asleep because if I do it when she’s awake she screams bloody murder
