I've had the devastating news my darling mum has been diagnosed with lung cancer today, she has a large mass in one and a smaller one in the other and it's sadly passed to her lymph nodes, I feel totally numb, my mum and dad have known for about 2 weeks and kept it to themselves as they didn't want to spoil Christmas for my sister's and my family, we both have children but my sisters are young and won't understand, my children are 17 & 13 and have guessed that something is up, I don't want to tell them the whole truth as it will crush them, I just don't know what to do? If anyone has any advice or is going through or gone through a similar situation and has any advice please help me.
