Don't despair , my husband was diagnosed a year gone April with no cure but the chemo and radiotherapy halved the tumour and he's still here with me.  It's a tough road and hard for carer's,  you MUST look after yourself ad well, if you make yourself in with worry its not going to be helpful.  There are good days and bad days, take it a day at a time, concentrate on each day only and get through it.  Use good friends,  go for coffee,  the pictures anything that gives you some respite.   My blog is a day by day diary of living with cancer.  Have a look at last May, June 2017 posts it may help.  Warm wishes to you.  Carolxx
