@Lynne48 I was sorry to read your news. There's so much for you to absorb. It sounds like you want to control your everyday life and have even put into this post your thoughts on funeral. My day job is running a Cemetery and I always advise people to put thought into what it is they want, to be cremated or to be laid to rest as bodily remains. That is the most important question as it is a difficult question for families if it's never been discussed. Once that decision is made, just make sure you have it written down or in your will or discussed with family so they are aware.
Now that we've been to the extreme end of it all I think your real priority to is absorb all the information based around what's next with your team and how you are going to manage treatment and working and everyday. Enlist help where you can both practically and financially. Take care
