I hope the best for you and your family in this trying time. It is hard to lose a parent.
My dad passed last August, massive brain stroke and I had to make the call. It was horrible, but he did not want to live that way.
My family, friends and PS friends helped me through it. We can be a very compassionate group here.
When you are ready comeback and kill some clackers or one eyed rats, that can be good therapy. Helps me at times.
Take care, keep yourself healthy (your family needs you) and hope to see you soon.
