Hi there and welcome to the forum. It's good that your friend has someone like you looking out for them. There's quite a lot of information and help with that and I recommend this link - https://www.cancerresearchuk.org/about-cancer/coping/mental-health-cancer that explains some of the reactions that people struggle with when diagnosed and dealing with cancer. There are places where people can find the support and understanding they need. I hope that helps and please keep in touch and let us know how things and going and if you need anything. Gill xx
