Hi Dee,
Sorry to hear your diagnosis, that sucks. It takes a lot to get your head around the thought of dying, I think the worst is worrying about those we love and have to leave behind. I have spent a lot of time thinking and talking about this and now find myself in a good space especially now I know the details of what will happen at the end with a GBM lvl4, once I was reasured I would be keep pain free and that it would be quick I found I could deal with it much better and also my faith has helps lots too.Good luck with you, I will be thinking of you.
Cheers
Sue
