For me, I learned at a young age, just to ignore my physical as well as emotional pain. Fast forward, and I'm working and although the emotional stress would be at an all-time high, I would just take it, because I believed I had to, in order to get that paycheck to survive.
The funny thing about it is that when the emotional pain became too high, then something physically would happen to me, like my wake-up call, where I could no longer ignore it, like having to have surgery, etc.
I made a promise that I would quit my job while I was in ER about 4 years ago waiting to hear if I was going to have to have surgery on my foot. I had just been told that I had broken a bone in my foot. I thought I had just sprained it. I kept that promise and gave my notice because I knew that I could no longer handle working where I was.
