Hi 

when I was 13 my dad was diagnosed with larynx cancer which metastasised and it was awful to see him essentially fade away before my eyes. It’s something I would not wish on anyone and I understand how much you and your family must be suffering at this time. You’re never alone in feeling how you feel, cancer is a horrible horrible disease that steals so many lovely people away from their families. Try to hold on to the memories you have of your dad before the illness, never let the new memories of suffering taint the old memories. While you may have to help your dad physically, he is still a strong person and a strong fighter. It takes great strength to fight such a battle and I’m sure he appreciates everything you’re doing for him while he’s going through this. Keep fighting with him, I wish you and your family the best. There are always people to talk to about what you’re going through <3
