Loss of an adult child

I lost my beautiful kind and talented daughter to stomach cancer at the age of 26 in October 2014. I see so many posts from people who have lost parents and partners to cancer but nothing from bereaved parents. I am struggling to cope with my grief I have two other daughters who need me to be strong I am divorced and am supporting a male friend who has just had his third liver resection for secondary bowel cancer. I have days like today when I can't eat or get out of bed but I have to work full time as a primary school teacher to support myself. I would love to hear from other bereaved parents who know what I am going through
