I understand not letting me go back with my mom In the ER and they said they would call me when she was ready but to interrupt me as I m trying to explain what is going on with my mom and the nurse turning her back to me as she rolls her eyes at me is not acceptable . After 3 hours I call for an update and they told me she getting antibiotics and still have a hour left to go and was told they would call me
My mom calls me after about hour saying she s ready
To go so I tell her I m waiting outside but I m still waiting for the hospital to call me
I look up and here comes my mom walking out by herself ( mind you she suppose to walk with a walker and supposed to be on oxygen )
No one bringing her out in a wheelchair or walking with no help and no oxygen. I was very frustrated with them
