This can be a really scary time for everyone. I don't know how close you are at this point, but having been through it, support comes so many different forms. Do what you can and be strong for the both of you, but don't ignore your feelings. It's important to know how this is affecting you too, talk to someone, post, it's so important. Listening too is an important form of support and you are doing just that which means a lot!!

This was hard for me and may be for her too, but I HAD to accept help at one point during treatments. I appreciated the offers when friends, who were absolute angels helped me out by taking me to appointments because I could not drive home myself. Then they would at times just hang out at the house to make sure I was ok after treatments. I felt badly with them doing this even though I know they offered, but I knew I was not ok as I would get really sick and dizzy at times; not everyone does but if you start to see this trend for her, this may be something you can offer to help with. They also helped to make sure when I got so weak that there was food in the fridge, and to make sure I continued to keep taking care of myself when I lost the energy to so with encouraging words.

Just some ideas that you do can do depending on how things go. The most important thing is that you care and you'll get a sense as treatment goes from her what you can do to help and how to show your support that's right for both of you. Your friend will be in my thoughts. Hang in there.
