Can you keep my dad in your prayers?

He is diabetic and his toe is getting black; he's getting seen today as to whether his foot can heal, or if there has to be an amputation on the toe. He can't feel his foot and we know that he's been having a rough time. He is 59 this year with dementia, as a result of TIA strokes, and he thinks we still live in Wisconsin, where we moved from 20 years ago. So it has been hard, but i am praying to maybe assign more angels his way. Thanks.
