Hi Marina and welcome to the forum. This will be a difficult time for both of you I am sure.  I travelled the road with my hubby for nearly three years and the forum was my sounding board and support when I felt unable to understand why I was being 'alienated' by my husband but he truth of it is that for all involved it is a frightening and worrying time.  My hubby struggled enormously with the side effects of chemo (some do some don't) and it was a learning curve as to when to take a step back (the more I coaxed the more low he felt so I stopped asking the constant questions and took the view that he would ask for my support).  He was on palliative chemo so was understandably  unhappy but in time we came to understand how best to support each other through.

What I would say is that it pays to note down any problems and report them as soon as possible to his chemo team as there are many things they can offer in the way of medication to help relieve side effects once they are aware of them (which unfortunately can build up as chemo continues).  Please come and chat any time as many reading your post will know only too well how it makes you feel.  It's easy to say but take time out for yourself too as this does help with the coping side of things. It may also help to mention in the title of your thread the kind of cancer your husband has, as this will bring other replies from those with similar experiences. Regards and a virtual hug.  Jules54
