Shawn,
It's stories like this that validate getting second and even third opinions. I'm so sorry this happened but as they say, hindsight is 20/20.
I'm fortunate that I listened to my gut when my journey started. I went to the local doctors and hospital and while I liked my ENT, I was not feeling it with the RO or MO. It wasn't a team approach and one hand didn't seem like it knew what the other was doing. There were some other issues as well but I won't go into it.
I sought a second opinion at Johns Hopkins and it was a no brainer. I'm convinced had I stayed local, I wouldn't be here writing this.
Trust your gut, research and have confidence in your team.
I can't say I have any real regrets concerning my decisions about cancer treatment. Now my second wife? That's a whole 'nother story! ~lol~ But then I've found in life that I regret more the things I didn't do (What If's) as opposed to the things I did.
Positive thoughts and prayers
