That last part is a good summary @sister. People always tell me I'm amazing but you're right, I don't feel amazing, I just get on and do it.
My relationship with my sister remains difficult but I hope we're making baby steps. My mother is a different case. It's not all bad but at 83 she has tipped into querelous old womanhood with huge side servings of passive aggressiveness, self-pity and a reduction in her ability to filter. Much of which I understand is normal at round about her age. I am striving to be patient but not always succeeding...
Now re counselling I want to say that it goes against my grain too. I'm from the school of putting my head down and just getting on with things. But the 'things' in my life have become overwhelming, so reluctantly, I have dipped my toe into talk therapy with a psychologist who specialises in breast cancer. I've only had two sessions so far, and am proceeding cautiously, but it's OK I think. I think you have to find a therapist you know you can work with, the chemistry has to be right. Can you ask a medico who knows you to recommend someone? I got to my woman via my Breast Care Nurse. Let me know how you go if you do. Hang in there.
