Hi Russell, I am so sorry to read this. My Dad was also diagnosed recently- it's a huge shock and the fear of what's to come is huge- I understand. Of course you will be overwhelmed- and managing 100 people at work is a lot. You must speak to someone senior and take a bit of compassionate leave - which you should be intitled too. This is so important. You need to process this. And I know it is a lot at your young age and With a little one who loves her grandfather- but you need to be positive and strong. Aware not much to feel positive about but try and enjoy time together with him- talk about other things- play a game.... Great that you are reaching out to a therapist. I also feel it could be good to tell some of the team you manage- you will find  support and they will (I hope) be understanding and perhaps eliviate some of your work pressure - and I am sure a few others may have had close ones who have suffered too. 
sending love and strength 

Hi everyone just thought it might be a good idea to update you all on my dads situation. Unfortunately it isn't good news  my dad sadly passed away last Friday. I my self have experienced a roller coaster of emotions. 
dad started his radio therapy for the cancer that spread to his neck and after his second session I believe his body gave up. We all didn't like the idea of him having radio therapy but it's something he wanted to do. I received a call from my mum on the 6th of august telling me she had to call a ambulance for my dad as when he exited the transport vehicle which took him to his appointments he sat out the house in the pouring rain and wouldn't come inside. Mum finally got him inside and unfortunately he was extremely delirious and confused and wet himself. That's when mum spoke to the Mac millian nurse who after briefly speaking to my dad advised mum to call the ambulance. Dad was taken of to hospital. He FaceTimed me when he first arrived and I see for my self something wasn't right. I received a miss call at 3:40am from my dad which i couldn't answer as I was asleep as I have to get up at 5am for work. The next morning I gave his iPad a call and I presume the nurses answered it and gave him the iPad he didn't seem right and wasn't making sense the nurses was washing him at this point. I won't drag on for to much longer just feel like I need to get this out. For the next 6 days mum was the only one allowed to see dad due to COVID which broke my heart as the day before my dad passed he woke up from being sedated luckily this was while my mum was visiting him and me my brother and sister was able to speak with him. He told us he needed us there and I hope he understood that we couldn't. The following day mum received a call at 9am telling her she needs to get to the hospital ASAP as they believed today was the day. I'm so grateful the hospital allowed me my brother and sister in with abit of convincing and you could say pleading with them they allowed us in to be with him in his final hours dad passed peacefully and I believe he knew we was there as he kept lifting his hands up slightly. Thank you for reading
