It is so very EASY to shame and blame the other people in our lives for virtually everything that happens to us and around us.
The hard part is realizing you are doing it, owning up to it, and stopping yourself each and every time it happens. I think doing so is a huge part of Recovery.
It doesn't matter where it starts, whether with an alcoholic, with you, or with anyone else. What matters is the sickness is creates and how much you perpetuate it.
There is plenty of it everywhere you turn.
