I’m glad to see you reaching out for help, it’s challenging enough trying to manage the diabetes, so I hope things are going well there. I recommend the same as @aakrzeminski regarding supplemental insurance through the state. Oregon also has a special program for kids to help cover costs, since a lot of childhood diseases tend to last a lifetime.
My son was diagnosed at the end of April and is 11, so I’m right with you in this journey, although our experiences will obviously differ. Feel free to message me and be sure to keep reaching out and finding your support network, especially with the costs. Best wishes for you and your family.
