my heart got broken today

As u can see I work on a hospital in executive admission area and as u know we are the first people u see when it comes to appointments and everything so today a lady came with her 4 years old girl and she was really nervous telling me she needed an emergency consultation for her daughter so I asked what was the disease or the cause of her visit and she told me : "my baby just feel sick", so I did all the paper work and the little one entered to the emergency lab ... Half hour later, my nurse friend tells me really angry and mad that the little one was abused !!!! I don't fucking believe !!! My heart literally broke and I felt so bad for her, don't understand why these things happen ! Obviously lots of things happened but I can't tell u more because of the confidentiality of our pacients but I feel terrible I needed to expose this. :(
