Penny,
I'm glad you asked the tough questions now, when it's 'safe' to hear the answers. Knowledge is always a good thing! And I know your onc is top notch. I'm also glad that you let us know that
(a) your scans on the 25th may give you great news (which is what I'm thinking will happen), and
(b) if the news isn't stellar...you still have options
Those two things, combined with your incredibly strong faith in a God who loves you personally and passionately...make me not so much worried about you, as happy to pray for good results and a peaceful heart.
I feel like you're not "borrowing trouble"...just gathering information.
It sounds to me like you're trusting that you're in good hands medically...but more importantly...the Lord has your back.
I love the Footprints metaphor...and since your legs have been so sore, I imagine one set of footprints and one set of wheelchair tracks in the sand. But, I don't think it sounds like it's time for the Lord to carry you yet.
Lifting you in prayer...as always
Sending love and light to you too...
Denise
