Angelicyang, every journey is different. I cared for my partner, Dennis, for 13 months and 3 weeks. He passed away 2 days ago after being diagnosed in early August 2011. I have to say it's not easy at times; but from what I heard from others, mine seems to be quite a pleasant one. You can read more from my blog here.
Dennis could look after himself up until 21 September 2012 when he had started to be bed bound after a few falls in one week. I had him home for a few days while being bed bound until Monday 24 Sep. He spent his final 4-5 days in an inpatient palliative care. You can see that I didn't have to suffer looking after him very much at all. The hardest part of this is the emotional side of it. Feeling helpless, feel that I did the best I could but I can't kill the disease for him and now that he's gone I just feel so lonely.
