Marion, I hope you are feeling better now. That was quite a horrible experience. I know it could happen to any of us.
You used your brain and did good. I am glad you made it up and out. Many people I heard this happened to, just sat is the water until it was freezing cold, cause they couldn't get up and out.
They froze for hours until help arrived. You were smart to pull the plug and get the water out. Dry the area to get traction. Your body didn't cooperate but your brain is working very well. Kudos to you Marion.
