Urgent Surgery Needed: Insurance Cancelled

A few months ago I went to my Dr with pain and unexplained bleeding. After a multitude of tests, imaging and visit's they had found several masses and cyst's on my ovaries as well as the bleeding causing an extreme level of anemia. The last visit I had I was green lighted for a total robotic hysterectomy. 5 days before my surgery I received a phone call from the Dr's office telling me my health insurance had been cancelled. I made several phone calls and finally got in touch with someone that said it was cancelled because I did not do my yearly review packet and so was cancelled and they would not reinstate. That was back in April. I have tried looking into other insurances as well as the one's you have to pay for, none would treat pre-existing illnesses or surgeries needed for them. So I prayed to the good Lord and this idea just came to me and then others suggesting it, I seen it as a sign. Any help in any amount would be a blessing. Thank you and God Bless.
