I'm a stay at home dad with a 2.5 year old Wolverine Tornado. I'm also a part time caregiver for an ailing family member and my dog just had spinal surgery.
Writing time is plated in Unobtainium.
Could you please tell me to shut up, sack up and go do it anyway? I thrive on encouraging abuse.
That said, always remember that there are others doing worse than you, and some of those doing worse have written and published whole novels. Sometimes more than one.
Life will not afford you sympathy breaks, and so if you want to do this thing called writing, you must snatch time from its crushing jaws and claim your career in whatever fits and starts you can manage.
You wanna write, write. Even if that's just 100 words a day.
And you can write 100 words a day sitting on the porcelain throne, so.
