Big hugs to you Nay. I agree with Michelle in taking everything one day at a time, it's worked for me. I don't get too far ahead of myself and find it easier to deal with the here and now. I too didn't find the surgery painful but make sure you get yourself a great lymphadeoma physio for afterwards.
Is hard not to compare your treatment with others, especially being diagnosed with the same breast cancer, but everybody is unique. Write down your questions and take them with you to your doctor.
I hope you have recovered well from your surgery.
