Support for Nephew's Cancer Relapse

Hello, I was given the privilege to take custody and care for my now 5yo nephew with multiple health/medical and behavior conditions. Unfortunately, the state (DCF) in which he came from has not provided me with support during this time. Knowing he has multiple genetic conditions, they processed everything incorrectly which denied me assistance in caring for him. He was diagnosed with an aggressive type of cancer 2 months after he came here. After surgery, 12 rounds of chemo amd radiation he seemed to be doing well. All of a sudden, i could tell something was wrong. He relapsed, this time in his brain. Surgery, chemo and radiation again. I am a single mother of my own child as well and this has all put me extremely in debt and still no help from the state. I am trying to do my best to care for him and the finances have caused a significant burden in our lives. Now going through this again and being almost 100k in debt due to the situation is making it extremely difficult. I am asking for any donations to help us through this long and unfair process that he is going through. Even past this, one of his many genetic conditions is a syndrome whic predisposed him to cancer, so unfortunately this will be a long upload battle for his entire life
