Hi, this is something that I'm actually looking for help with as well. I have a family member who has just been diagnosed, so I came on here with the hope of being able to get in touch with some people who were in the same kind of situation as me. I want to help as much as I can, but I also know that I can't afford to give up work, so I'm hoping that there are other kinds of support that you can get as well. I'm not entirely sure though, so if anybody could give me a little information that would be great!
The best thing that I've found so far is to provide as much emotional support as you can. The doctors deal with the medical side of things, so that's sorted, however your friend/family member still needs to feel "normal" as much as possible, so try and give them that sense of normality.
