How do you try and keep things as normal as possible for someone with a terminal illness?
To keep things normal, just be normal. That's how I did. My partner and I would talk about his prognosis and chance that he wouldn't be a survivor. We cried and screamed together while at the same time we tried to be optimistic. You never know there might be a miracle or any new drug discovered. I think it's not bad to be realistic about the situation but also keep your head up. We agreed on talking openly about how each of us feel and cry if we need to as a way to let things out of the system. There is no need for you to be strong for your dad. He would be more than happy to be the stronger one to support you even though he's the one that's suffered. I told my partner that he didn't have to be strong for me and could cry with me but after all this we would continue to fight.
*Also how do you boost someone's moral when they have a terminal illness?
It's nice that you try to be there for your dad. From the sound of it you don't have to raise his morale. Perhaps he can come to terms with his future. My partner was always optimistic and continued to fight up until the day he died. Just be there for him is the best you can do. And for sleeping a lot even with little physical activities, I think it's normal side effects from all the treatment. My partner spent a lot of time in bed/couch resting during the day.
How do you handle this situation with your employer - is it possible to take planned carer's leave as I have several weeks entitlment accured?
You have to discuss this with your manager and hopefully he/she will be very understanding.
My manager is very understanding even though his hands are tied with all the policies and procedures as working for public services. I was not allowed to do work from home but I can do flexible work hour. I was allowed to use personal leave (carer) whenever required up to the limit that I accrue. I could work long hours and use those extra hours to take time off here and there. In the past 14 months through this journey, I only used my flex and personal leave to spend time with my partner looking after him. I am lucky, he was very independent up until the last week of his life so I could manage to work full-time while being his sole carer.
