So close to the surface

In my cocky days, I sometimes pushed myself too hard, on a verge of passing out as I came up. I wrote this fictional short story to a diving buddy to remind him and myself that abalone diving can be very dangerous if you get too greedy.
"After executing a perfect pike diving position, you feel you body submerging completely underwater effortlessly. After a few dolphin kicks and clearing your ears, you find yourself 15-20 feet underwater. To stabilize yourself, you grab one of the bull kelp stalks scattered about before hunting for 'hubcaps', round shaped thick abs with meat sticking out everywhere. You see a 9 1/4" ab wedged between two small rocks. After the failed initial attempt, you managed to pop it with some extra effort. Feeling ecstatic, you begin to accent. Something is tugging on your right leg. You look down and see that one of those skinny rope-like seaweed is wrapped around your fin. You try to break loose but it seems to get worse. You kick again with no avail. Panic sets in but you don't want to lose your ab so you kickwith both legs like a madman, using up valuable oxygen. The fin finally comes off. Your lungs are burning like fire. Only 5 feet to the surface.. Suddenly everything goes black. You just experience your first shallow water blackout. Your body begins to descend from wearing too much weight. Coast guard finds your body later in the afternoon. You still have your 25 pound weight belt on, and they had to pry you mouth open to get the snorkel out."
