My mum has just been diagnosed with lung cancer and cannot have surgery or chemotherapy, she has been given 18 months to 2 years and she has already had 2 chest infections and now she has another so am scared of losing her. My dad died of bowel cancer, my nan died of bladder cancer, as well as my other nan died of blood cancer then my grandad died of a broken heart so there is only me my daughter and my mum left in the family so if you can understand why I am very scared of losing my mum there will be only me and my daughter so please help as I have been very depressed and now I have started smoking to ease my stress. Also I am not very well myself and now just found out I have lost 2stone in weight in 2 months because of my stress.
