This is something I had wrestled with for a few years, and your right it is a hard one to get past. My whole ordeal started with a doctor making a mistake. Before this I was in the gym 4 days a week, and working in a career sent from heaven.
It took this guy one oops, and life was forever changed. I knew I had to forgive to get passed it, but it was the hardest thing in the world. But if you keep those feelings it will cause more damage than the damage already done. It doesnt mean you have to like the person, just means you forgive so you can move on with your life.
It took almost 4 years to find out what exactly was wrong with me, and once it was explained, I was devastated to find out that he knew the whole time. They could have started treatment right away but denied everything. This news was almost worse than the actual physical damage.
Hopefully you can find an attorney and do what I couldnt. They should never be able to avoid the penalty for hurting someone, then avoiding or side stepping the problems they caused. I will be praying for ya
