I'm sorry if this comes across as crass (maybe you have a severe phobia) but to be clear, you panicked and thought you were going to die while at the halfway point of trying to cross a pool only 8 feet wide? even thrashing about should have been enough to get you across the remaining four feet to grab an edge, no?
Yeah it was 8 feet deep (I mentioned my height for reference).
I don't have any phobia of water. In fact, a week after the incident I signed up for more swimming lessons (8 1:1 sessions) and I believe I'm a pretty decent swimmer now.
I was actually planning to start training for the Alcatraz swim but moved out of the Bay before that could happen!
