Hello TracyB and welcome to the forum.  This is the most awful situation that you are finding yourself in; and you are having to hold everything together for the family.  It sounds as though your husband's condition may be deteriorating faster than you had imagined.  Please do take all the help you can get; are you having nursing at home?  Do talk to the nurses here (Freefone 0808 808 0000 Mon-Fri 9am-5pm) and the people at MacMillan cancer Support (Freefone 0808 808 0000 Mon-Fri 9am-8pm) For help and information whenever you need it.  I am attaching a link to the CRUK website about brain tumours; I don't know if some of this may be helpful to you.  Please keep posting here if it helps at all.  Annie
