Fear of ACDF surgery

Next week I am having ACDF surgery. C2 - C6. I have had neck and facial pain for over 2 yrs. When this started I went to my GP who I had for over 30 yrs. For some reason the doctor I met that day was not the doctor I knew. He had always been helpful, would go the extra mile for anyone. Heck, one year my husband and I nominated him for doctor of the year at a local hospital and he won. That day was shocking to me I told him how I felt. He did not check my neck just leaned against a wall and said he did not learn about this in medical school. He went on to say that if I go to the hospital, they will tell me to go back to my doctor, he said don't. Needless to say I was in shock. Fast forward I saw a few different types of doctors...none of which showed any concern. I was told I had TMJ, I needed a physiatrist, I needed my thyroid removed, nothing was wrong with me etc... But nobody opted for x-rays or an MRI. At this point I went back to my GP. He agreed to see me, but said he would not talk to me about my neck. My husband asked him for a referral to see an ENT. He said he had no reason to do this. It would be embarrassing to him as his integrity was on the line. My husband begged him, he finally agreed for a referral. The ENT put a scope down my throat and said nothing was wrong, he didn't see anything.
My second to my last stop I thought I finally found hope. An MRI was taken. I was told nothing serious. They referred me to physical therapy for 10 weeks. The doctor did note to me that he disagreed with the radiology report. He said he saw a Chiara malformation and wanted to me get a second opinion at a local university hospital near by. No one called. I found another GP, who I explained all this to. She set me up with an ENT. The ENT showed me my MRI and another MRI of a person who had a Chiara. She said I in no way have this. She went on to say at my age I would have known by now if I had one. What a relief. Finally I decided I needed to explore outside of my city for help. I went to Des Moines, IA. There a surgeon looked at my MRI and he also order additional x-rays. My problem is that I have a nerve impingement between c5, c6. I have stenosis and arthritis in the front of my neck. I needed surgery.
I have been through hell for the past 2 plus years. Isolated, in pain and on my own, searching for help. I've developed depression and anxiety. I am a reck. My surgery is next week.
