Grieving takes many forms and it the different feelings can just come up at unexpected times or not at all.
I wasn't angry I got breast cancer.
I was angry I hadn't taken the time out for genetic testing as my job was so busy. But it turned out I wasn't positive anyway.
I was angry I stayed in a job that ruined my life for a time and gave me such awful stress and exhaustion I believed it gave me cancer.
But honestly that was for about a week.
I never had the "why me" as I always thought I might get breast cancer. I wasn't surprised to find the lump. I had a clear idea what I wanted.
I was however devasted to have cancer. Frightened of dying and leaving my family and sad for the loss of my breasts and the flow on from that. I don't think I had denial either. I accept I might die of breast cancer. But I've made the decision to believe I'm cured until things prove otherwise. Worry just sucks the joy from life.
I think we shouldn't over analyse. Just let the emotions roll. Acknowledge them and keep going. If you get stuck...that's when you need help I think to talk things through.
