How do you navigate cancer treatment without insurance?

I was diagnosed on January 15 after being checked out for a car accident. I have all my car accident injuries head trauma, sprains and such. I have had my PET scan and last weekend my MRI. I don’t know the results of the MRI yet which will determine if I’m still stage 3 or 4. I practice holistic therapeutic methods most of my life. So I haven’t carried health insurance. I have paid cash for all this cancer diagnosis and my injuries from the car accident was being covered under my auto insurance. I can’t get answers as to how much the immune therapy will cost because of my staging. It’s been months since my 2 biopsies came back both positive. My friends and family are frustrated with me and think I should have more answers by now. It seems I’m at the back of the list since I don’t have insurance and money is tight. I don’t qualify for Medicaid and since being diagnosed I have a preexisting condition. I’m sure I’m not the only one that has ever had to navigate through this. Holistic clinics are also way more than I could ever afford not to mention nothing is located where I live. So I have been going the cancer hospital in my area. I feel all I do is wait. I’m in so much pain especially on my left side. The melanoma is also on my left arm a site on the front of my arm and the back of my arm. Both were cut for biopsies and have been growing back since waiting. It burns and itches all the time. I’m praying and feeling like no one understands. I haven’t really processed that I have cancer since most people say it’s just skin cancer you’ll be fine. Thanks for anyone who reads this. I’m just alone and it’s fine. Needed to get it off my chest. 🤍✝️🙏🏻
