Brandi, it is hard, I know, to watch a loved one turning into a shadow of his former self and to know that we, as caregivers, have already done everything we can to help. The day I heard that the MO wasn't going to give my husband his third chemo session because he had developed deep vein thrombosis and that his blood counts were all too low anyway, I sat in the waiting room and cried. It felt like I had failed him in some way, when intellectually I knew that it had nothing to do with whether I had put in enough effort. It was probably the worst moment in all of the seven weeks. Then I picked myself up and got back to the care-giving. It is truly like a roller-coaster ride.

Don't forget to look after yourself as you go through the journey with your dad. Exercise -- maybe a bit of walking everyday -- eat and make sure you get adequate sleep. Being physically well with help you deal with the emotional upheaval.
