No worries hon
And please don't think I'm trying to dismiss your concerns, because they are all quite valid and very similar to my own.
But when I get to a point where I can't see the forest for the trees sometimes, I just remind myself of the Baby Bird analogy....
Momma Bird is up on a high branch with Baby Bird.
Momma Bird says to Baby Bird "OK Baby Bird, now it's time for you to jump."
Baby Bird looks at Momma Bird and says "But Momma, I'm scared! What if I fall?"
And Momma Bird replies "But oh, my dear! What if you fly?"
