Oh dear, I am not surprised you are angry.  I don't know how much difference the delay has made but I get it that this is not the point here.  I can imagine you are having trouble separating your anger from your distress but - with the the short timescale you have been given - this is where your energies need to go.  Sorry if that sounds a bit bossy. Gather your resources, family and close friends, to help you.  Take care of yourself so you can help your partner.  Easier said than done I know.  My son's father died from lung cancer - he wasn't with us for long but that was partly because he delayed in asking for help.  But everyone concentrated on the current situation to make things easier for him.  Macmillan nurses were great.

You must be feeling more awful than I can understand.  I am so sorry you have found yourselves in this situation.  Best wishes.

Hi,

I'm not surprised that you feel angry, I did for a while when I was first diagnosed at stage 4 after several trips to and from my GP. It may be that, like me, your partner didn't show all the classic symptoms of cancer and was given an incorrect initial diagnosis as a result. My own symptoms exactly matched a peptic ulcer with no weight loss at all with high energy and fitness levels. 

Annieliz's advice is sound. You need to prepare for the worst, whilst hoping for the best. This may seem hard-faced and will be the last thing on your mind but if he is your partner and not your husband you should make sure his will is up to date and reflects his current wishes. The legal position of common law partners isn't strong if someone's estate goes to probate. That's all part of preparing for the worst. 

Hoping for the best - has your partner been given a care plan yet? Ignore any doomsday scenarios the medics might give - that's just one worst case possibility which probably doesn't take into account the potential impact of any proposed or planned treatments. A lot of people are so devastated by hearing the worst case scenario that they choose not to have treatment which offers a small but significant chance of survival. My view was the odds were stacked aganst me but any hope was better than no hope. 

Best wishes and good luck

Dave
