I'm hoping someone will be going through similar as I feel very alone.

I'm 20, 21 next week and my daddy who is my bestfriend is in his last few days / hours. He got diagnosed 18 months ago, I have been with him every day since. My mum is a nurse and giving him all his care and I'm at uni studying paramedic science, I am now helping my mum too but it is the most confronting thing watching my dad slip away from me and lose all awareness. He still smiles when we talk which is giving me hope, I am very much in denial but I'm so heartbroken. My family dynamic has changed dramatically as my older brother couldn't cope so walked out. Me mum and dad are so unbelievably close and life is so unfair. My mum and dad are still so in love and the devotion from mum is admirable, she is going to be so lost and I'm so worried for her afterwards as I know she won't cope without him. As mum is a nurse and giving dad all his care, we have been left alone pretty much and I feel I need someone to talk to now, I've tried to be strong for mum but it's hard.
