Help Gracie

My sister Ruth needs help. Her daughter, my niece is on life support. Her name is Gracie and she is 6 years old. Not sure why at this point but her body started shutting down due to an infection that the doctors aren't even sure what it is. My sister is a single mother of 3 with limited income. Right now she's at the hospital until Gracie gets better and is unable to work. I was hoping we could pitch in together to help my family out. Every little bit helps and we appreciate anything that you can give.
