raggie, try to rest assured that our "Positive Thoughts & Prayers" will be with you, your mother, & family!
We're born in a body that starts to "wear out" when we take our first breath. Technology has come a long way in helping to identify, cure, and prolong the shell that we live in (as well as create some of those problems that we seek to reverse or deal with). However there is more than technology at play here in this mortal world.
Call it "Positive Thought (positive mental attitudes are proven), Prayer, Miracles, etc..." It's real! Though we of course sometimes have a hard (if not impossible) time trying to figure out "The Plan" - I believe we aren't always meant to understand "The Plan".
We all have a mission here on this mortal earth...it's not always clear why things happen or who they may affect.
What am I saying? I beat around the bush too much! I certainly believe that God (I call Him "God", others may call Him something else - if not an actual "name", then they may say "Karma" or...??? Even if they don't believe in "God", they may believe in "Themselves"...I'm not meaning to start a religious discussion here) is in our lives, we and our lives are His Plan and it's certainly hard to understand at times!
He is certainly with you, your mother, & family and so our we!
