Interesting post about unfairness as I discussed it with IC. IC told me that dwelling on the unfairness is like drinking poison as it only hurts me not ex. Like you I feel all this in unfair but IC that life is unfair so we have two choices: being miserable about the unfairness or realising that it's out of our control and carry on forward.
I agree with Ginger that it might take time but we will eventually get rid of that feeling too.
