How do you deal with both your parents being seriously ill?

This is my first attempt so please bear with me as far as spelling, punctation etc.

Within the last 3 months my life has changed beyond all recognition.

I took on a new job, moved over a 100 miles from my partner and friends, this i could have dealt with. Unfortunately i hadnt banked on my mum being rushed into hospital on the first day of my new job. We knew she was ill but had been given a diagnosis of diverticular, a stomach complaint, that although grim to live with is not neccesarily (so far as i understand) a killer. Well it turns out she had ovarian cancer that due to the length of time it had been left untreated had spread to her lower bowel. By the time i arrived at the hospital she was due to go in for surgery, she had changed beyond all recognition. Gaunt, emaciated and so frail it would be hard to realise a year ago we had walked along a beach together.  Even this i could deal with.

My new employers are not the most sympathic people, although they havent said im not allowed time off to look after mum, life has been made very difficult. Mainly by a person, who shall remain nameless, suggesting that i ought to leave, for my own sake of course!

Okay so im still dealing with this situation, and all the emotions that go with it, when dad is rushed into hospital with a small but very real heart attack. Of course i rush to see them. Mums too frail to be left on her own and i need to see my dad. Fortunatly he was in time and a stent has been put into his ventrical. He wont rest and he wont ask for help. Im at a loss! I live around 250 miles away, i cant be there as much as i want/need to be.

so my question to you all is do i

A) Quit my new job and move up with mum and dad for what could potentially be the last few years of their lives, as mum is coughing up blood and dad refuses to take it easy.

B) Tell my employers if they dont like me having to take time off, tough tittie, they can either dock my wages, take it off my holiday or i'll work the time back

C) concentrate on my new job and hope that its not as serious as it feels?

Ive never been so lost in my entire life, my partner is hopeless in these situations. I saw him last night for the 1st time in nearly 2 weeks. He talked to me for over an hour about his day at work without once asking me if i was ok, how was mum or dad and wouldnt have bothered even finding out if i hadnt said.

Although this is not "news" in the sense of any world changing events globally, its the biggest news in my life and any words of advice gratefully recieved, thank you for taking the time to read this.
