What is fair amount?

In November 2015 I was driving truck making deliveries, as I was pulling off pallet jack it got out of control, so I had to jump off of the liftgate when I did I actually broke my right heel bone. What a recovery I was just released by Doc in Sep with a 15% loss in that foot, it still gives me trouble at times with pain and I am also told that there will be good chance of chronic arthritis setting in. Not sure when I could actually jog or run again, I can’t imagine putting that kind of pressure on my heel. For those of you that has not heard of a heel break let me tell you it is unbelievably painful, I read it’s one of the worse breaks with about a year recovery time, luckily I did not have to have surgery but it was a complete break. So I have been on workers comp since it happens and just recently received a letter wanting to settle, but with any settlement my company wants my resignation which is why I am asking this, they talking settling in the 30s it started in high 20s I got them up to 30s with easily, which has me thinking I may could get much more, I am trying to keep a lawyer out of it if I can, I was told I could maybe get 100,000 for it since my company has no job for me anymore, just wondering if anyone knows an amount I could get for sure I’m in NC, I will say I’m sure this will bother me rest of my life I’m 46.
