Please help me fight shingles and agony

My name is Joshua Cartwright. I have, for the most part, everything I could ever want: a fiancé who loves me dearly and my pup Bear who adores me as much as I adore him. We do okay on our own and we don't fall behind on bills. But recently, I've been in the emergency room several times over the past couple of months with issues with my head. Severe headaches that would not let up, causing me to miss work and fall behind. I had an ultrasound done on my lymph node and they found a mass, so they set me up an appointment with an MRI. However, I didn't know that my stressing about possibly having cancer weakened my already poor immune system. After my MRI, my headaches were worse than ever and I had to go back to the ER again with no answers. The next day, I woke up with loss of vision and a splitting headache unlike any from the weeks prior, and now I had a rash. I went in and was diagnosed with shingles, and not just rashes and blisters but extending into my eye and skull. Shingles is a nerve virus that causes intense pain both on the surface and the depths of the site. I am now completely incapable of work. I cannot look around without suffering pain so terrible I could pass out. I can't even lift a coffee cup without the strain, though small, causing a huge attack in my head. I was guided to use vitamins and herbs to help fight back, but they are so costly. $100 got me 3 days' worth and I need 3 months' worth. I've been to the hospital so much for all of these issues, I have hospital bills piling up, and if I don't pay them, I can no longer be seen. I ask and pray that anyone who can help, please help me. I don't want to become a financial burden. I don't want to be the cause of my once normal life now crumbling. I know it's not my fault, but I feel so depressed that all I am is a burden and a walking mess of issues. Thank you all for the thoughts and prayers, and if anyone is to donate anything, thank you so much.
