I am so sorry to hear about the passing of your mum. sending you my love and lots of hugs. first few months after my husband passed away I felt like I was getting on starting a new way of living without him and all of a sudden one day the pain of missing him hit me and I started grieveing for him again. I say again as I know I was grieving during his last few months. It is now just over 18mths since I lost my husband, I still miss him and I probably always will. I lost my mum (not to cancer) approx 15 years ago and I will always miss her also but the days get easier over time and things doesn't hurt as much. I find there are days or things that are emotional triggers, I now try to look on these as times when I remember the good times and allow myself to cry if I want to.
