Insurance won’t cover my wife’s treatments.

Hi, My name is Eric, and I’m a FireFighter. I have never asked for help from anyone but God and I have a hard time doing this but I don’t know what else to do. I pay a lot for insurance but for some reason they won’t cover my wife’s cancer treatments. I have exhausted all my savings and I’m starting to sell off my things to cover these treatments. Sometimes it costs me 400 to 600 dollars a week for Treatments. She doesn’t want me to do this because of her pride but we have to be realistic. Without these treatments I don’t know what I will tell my kids and I know it’s my responsibility but I don’t want to have to explain to my kids that their mother is not going to be around anymore. Thanks for your support. You are very much appreciated. God bless you.
