I'm sorry you are in this situation. I applaud your self-awareness, and suspect you have enough skills and discipline to turn this around in the next few years. You may never get to the point of having millions tucked away for retirement, but do hope you can get to a point where you do have 'significant savings'. I'd measure that by your measure of 'extremely scary'.
My wife and I have no kids, so 'saving' has been somewhat easier 'by default' than some of our peers. That said, it's not automatic, and I know plenty of folks who are high earners who will manage to spend it all without 'significant savings' to speak of.
