I don't think anyone was talking about saving oneself. We were talking about holding on....
IMO, it's good to clarify, as many either teach that if they can't find some way within themselves to "hold on to the end" they're lost, and/or use language that can sound that way if not clarified. It's possible if one hasn't seen that extreme side of churchianity and/or experienced it themselves, they may not realize the confusion and carnage left along the roadside of such beliefs.
I was sharing personal experience, as that's where I've spent the last 20 years coming from.
I keep forgetting that many here have had those experiences. so it's a bit of a mystery to me. For me, my relationship with God is so personal, I would never let another define it for me. Recently, he's been showing me that he wants me to ask him for help with even the minor details of my life, whereas I have always been reluctant to ask for anything other than the most important--and I have enough of those to keep his angels busy lol. But, when Peter says, 'Save me, Lord,' he is asking for help for what is going on in the moment--not asking for something eschatological. And, Jesus doesn't hesitate to reach out a hand for Peter to hold onto as he sinks under the water, as if he would ever answer, 'save yourself.' Our Savior is so wonderful.
