Today me and my sister were told my mum only has weeks left to live. The doctors have messed up everything with her cancer and ignored all the signs that to us, seemed so obvious. I'm 20 and my sister is only 23, and I feel awful. I feel so guilty for not doing more, not fighting for her more, not spending enough time with her. I just feel so terrible. I don't know what to do and all I want to do it spend time with her but she's in hospital/ a hospice until she dies. I just don't know what to do with myself. I feel so helpless
