I suppose I could say that I have regrets about a few things... At the time I made the choices, they were the best course of action I had at the time with the information I had at hand.
Could I have done things differently or better? Sure. If I had the choices & same info would I make the same mistakes? Probably.
Don't worry about it. Make the best of your current situation, make good on whatever you need to if/when you can.
Be sure you're doing the noble thing & you'll have no regrets really. Keep in mind the good choices are not always the easiest solution.
