Good on you Lisa for being there for your friend. She is so blessed to have you. Also welcome to the website. If you have any questions you need to ask then please ask away.
I have a couple of very precious friends but unfortunately they aren't just around the corner for me to call on them and for them to be there for me when I need them. I am able to stay in contact by email and phone and they are such wonderful support for me. I was diagnosed with breast cancer November 2011 and currently going through chemo and will start 7 weeks of radiotherapy mid July.
All I can suggest is that you be a shoulder for your friend to cry on, an ear to listen to and not lecture her or judge her, someone to bring her meals, shop for her, help her around the house, organise someone to do ironing and all of those lil things that as women really get on top of us if it isn't all done and organised. Also as Shaz says all those other important things that need to be done. Please ensure you don't take on the whole load yourself, delegate to her family and friends so that you don't become overwhelmed by it all. Be there for her but not at the risk of your own health and life.
I have found one thing I struggle with is if I tell someone I have a sore back or a this or a that. People will cut me off half way through my sentence to tell me how sore their back is or whatever. I do feel like saying sometime BUT at least you not going through cancer.
There will be times when your friend may struggle to hold a conversation and if that is the case just enjoy the silence. Sometimes she will just want to be alone in her own misery and that isn't a bad thing as long as it isn't all the time. Sometimes she will have days where she will just want to sleep. Other days she may have a melt down. Unfortutunately it is all part of the course of this horrible disease and journey we have to travel. Some people cope better than others so I wish for both you and your friend that your friend is a lucky one.
Good luck and take care.
Mich xoxo
