@Mellyb my sincerest love and condolences to you on the loss of your incredibly courageous Mum. I lost my Mum 11yrs ago to an unrelated cancer to her BC of 26yrs previously. I can honestly say I know how you feel, it is damn hard on so many levels. I didn't have time to spend with my Mum she was gone within 6 weeks of diagnosis, leaving us all in shock and pain.
What an amazing daughter you are! hold onto your beautiful memories, I too know that she absolutely isn't far away, and it's something you never get used to, you learn to walk through life and move forward somehow with it.
Sending the biggest hugs to you. M x
