Glad to hear you made it - the will to survive makes all the difference in situations like that. You did all the right things and that isn't always easy when the sh*t hits the fan - it goes downhill in a hurry.
I would also guess you got to see what I call The Big Movie, too - when your life from start to finish literally flashes before your eyes in a microsecond. It's a real moment of clarity but I don't recommend it - I've gone through it 3 times.
And at 60 years old, that's good enough for me - I really don't care to see it again.
I lost a good friend in a very similar situation on Washington Ledge and the loss still scars family and friends almost 20 years later. I've come close to losing four others the same way on Brenton Reef to a rogue wave.
Give thanks to whomever you feel was watching over you.
