it sounds like it was all covered pretty well. good job keeping cool. If your going to keep spearfishing, it is always a good idea to have a spotter diving with you and rotating off who is shooting to avoid these kinds of mishaps. its already been said, but i will say it anyway, never attach your catch to you. I used to use a line connected to a quick release on my BC so i could maintain both hands free but ditch in a hurry if needed withouth the risk of it getting tangled. Good luck
