So hard so sad

Hi all my mum passed on the 25th November, her funeral was 13th December ,  she had lung cancer but it was stable for 2.5 years , and then October it went to her brain, - she had full head radiotherapy , this was heart breaking all she wanted to do was fight this, and the night she passed she was taken to hospital with pneumonia a really bad cough, which her partner had been on at the consultant about - and they said it was all to go with her brain lesion and the radiotherapy on her brain -  it turned to sepsis pneumonia- me my sister and her partner were with her in hospital when she took her last breath,   Here we are 3rd of January , and I feel so empty  life will never be the same .  My dad passed away very sudden when he was 46,  over 20 years ago-  my mum was 68- it be her 69th birthday on the 10th January,  I just feel like everyone is forgetting my mum - like she will be forgotten -  crying every day - the pain is just awful - xxx. I know it will get easier -  but it just hurts so much, my poor beautiful mum xx
