It honestly depends on an individual's perception of the fear they're experiencing. Fear of the abyss could be linked to the fear of drowning if you fear the abyss because you might go down so deep you'll never be able to reach the sky again. That terror that fills you as you think of the water pressing in on all sides, getting heavier and heavier. Sinking slowly, the world dragging you down to its very core.
But you could fear the abyss because it is a vast and unknowable space. The ever deep where creatures your imagination conjures in its darkest hours can come to life. Monsters with eyes the size of houses. There's always a bigger fish...
