Help My Nephew, Jacob!

Most of you know my nephew's story, he was diagnosed with a brain tumor when he was 13, had the first surgery and has since had numerous surgeries and treatments to try and keep the remaining tumor from growing and try to help control seizures, So far NOTHING has helped the seizures, thankfully the tumor is not growing, Jacob and my sister are headed to Chicago on the 20th for at least a week to a seizure clinic with the hope that they can help! I am trying to help with the money part of this journey, I hate that money is what they are concerned about!! Not only being out of town but the fact that insurance may not cover all the costs! Any help would be greatly appreciated, as well prayers lots of prayers!! I want nothing but alittle peace for my nephew!
