My boss knows that if I say I'm sorry I'm really saying fuck you , or I'm not sorry but I want to fuck again. So I kind of tease her, but then when we're actually fucking I say I'm sorry and she goes NUTS!
I think you should rethink your odd preoccupation of saying "I'm sorry" for endless things. I have concerns for you, only because you seem detached from what your future holds. You will be walked on, laughed at, kicked to the curb, and will never get a raise. Your Doctors will not fight for you to get better, if they think you are too nice to stand up to them. You sound real sweet, but also too naive. Find a balance, and try to have a whole lot more self esteem, and not be so concerned with making everyone happy. If you are young, you will find this helpful in communications and business skills. Nice is nice, but sensible is better.
