Drowned out

A diving trip gone wrong, but maybe not completely.
Leona Has been going through some things and diving was the one thing she did to escape it all.
But, when a trip goes wrong and she ends up separated from her group, under the waves she will have to make up her mind whether to stay or go.
If she doesn't leave it could change her life exponentially.
