My dad is terminally ill with metastatic colon cancer and they (the drs) told us In August that we were likely to have 18 months with him but despite palliative chemotherapy his cancer has continued to spread and we're now looking at a few short months at best.
He's gone downhill so fast since they told him the latest news and is sleeping about 80% of the day and in so much pain when awake 
I just don't know what to do to help him. He's always been a giant of a man (over 6 foot tall and 20 stone!) and he's now skin and bone and about 9.5 stone! His hair is all gone now and he's just grey in his skin, dark circles around his eyes and so weak and tired... it's so hard to see him how he is now but I'm so scared to look away and I feel like I'm holding my breath and hyperventilating at the same time...
I'm working full time and I'm spending most of my outside of work time in my parents house and trying to help my mum as much as I can as she isn't well herself (early heart failure)... it's just awful and I don't feel like im helping at all...
I'm so angry and sad! He's 63 for gods sake! We should have another 20 good years... we should be celebrating so many more birthdays and Christmases... he should be singing loudly to Elvis cooking another 20 Christmas turkeys or complaining about football and politics while we roll our eyes at him for so many more years. I shouldn't be preparing to say goodbye to my dad, or preparing my daughter to say goodbye to her grandad at 15years old... I shouldn't be holding my mums hand through this horrible time, being the google buffer when she's scared to death of what she will find if she types medical terms into her phone... I shouldn't be begging my siblings to visit him as I'm so scared they'll miss seeing him for the last time.
This is the worst of times in my 39 years and this isn't even the worst of what's to come... how do we do this?
