Joelle, I agree with what has already been posted here, hon. I truly believe this happened at this particular time so you could be where you will be needed most, with your Mom.
I moved my Dad home on Dec 10th 2004, as he could no longer live alone. He was diagnosed Feb 2003 with lung cancer. On Dec. 12th, shortly after I got to work, I slipped on a set of newly rebuilt stairs and broke my ankle.
My Dad died on April 3rd, 2005.
If I hadn't taken that particular little slip I wouldn't have been able to be with him.
My doctor cleared me to go back to work the week after he died.
I do not think this was a coincidence. Sometimes you just have to believe.
You have the wherewithal in place to help you and I truly believe this will be a good thing for both your physical and mental health!
