Falling Downward

I had a dream last night I was floating in a body of water, and I suddenly flipped over & was staring down into a cavernous abyss.  It was deep blues & black, and foreboding.  I startled myself awake.
I realized it was a reflection of how I'm feeling.  
I'm scared of falling into the abyss.
My blood pressure is up.  That terrifies me.  I'm afraid my blood work will come back with even worse news.
I constantly fear I will never live out my dreams to see the world.
I'm in fear of not experiencing the world with my kids.
As much as I love the water, I don't want to drown.
