11 year old son with brain mass

My name is Danielle and I am a mother to 4 wonderful children. My son Evan is 11 years old and is going through some medical difficulties that I am struggling to pay. I am a nurse and work two jobs trying to make ends meet. He was recently diagnosed with a mass/ possible tumor in his brain on the Pineal Region. We are awaiting results from the tumor board. This is causing my son and his body to grow to fast. He will need to recieve Lupron injections to stop the rapid growth. He is being seen by oncology for all of his abnormal labs in hopes to reach a stradegy to tackle this new medical complication. Each injection cost about $2900. Which we are still dealing with insurance to see what will be covered if anything at all. Unfortunately until that clears up, I am expected to pay out of pocket. Each one of theese injections are anticipated to be given monthly. Along with this high cost injection, I am paying $75 for each co-pay. At this point we are going to the doctor 2x a week following up with several doctors. He is a young loving boy, amazingly smart, full of energy and love. He sadly is old enough to know whats going on, but too young to understand that I may not be able to afford to take care of this situation. Having to ask for help fights against all my pride, but for this little boy or any of my kids, I need to do this. Any dollar will help out our family in this difficult time. We thank everyone for their support....
