Ack, allme!!! You are
not a bad person!
You know... I was thinking the same thing about myself this morning, and am trying to keep it in perspective by remembering how much stress I've been experiencing for such a time now.
YOU are experiencing far more!!! It's like a pressure cooker. Stress can really mess with our heads. If we're prone to self-blame, it sure can flare up at such times. Please don't take it all on your back.
(p.s. Great strategy for your Dad!)
