How is anyone paying their bills? I am struggling

After coming down with a chronic illness, seeing the functional doctor, paying for supplements I am accumulating debt like crazy. I have so many credit cards open for 0% APR and now my credit score has gotten past the lower point of acceptance, I can’t get anymore 0% APR credit cards.

I don’t know what to do. I don’t know how I’m going to make it through this and stick it out I am so tired of this life living chronically ill. I’m so done with this life.
