C2,
I can relate tot he choices that one must make when funds are limited by unemployment. I was there over 2 years, but each time it looked like the walls would lean in, something came in by way of contract work to ease the burden.
May the Lord help you find creative ways to address your finances to get to see your Dad if only for one last time and that it be when he has a "good day."
My prayers are for peace for you and for him. Parkinsons is a nasty bit of business, but your worst enemy right now is self incrimination and guilt.
Keep the Son in your eyes and seek God's will in this time of challenges. Prayers for discernment and peace, brother.
