Regret?

Is it possible...is that the word I'm looking for?  I don't know...perhaps I should explain the scenario and then you can tell me what the right word is.

Once upon a time I made a decision.  It was a very painful decision.  It was also the right decision.  But so often I regret making that right decision.  Is that right? Is that possible?  Can you actually regret a decision that was right?  Perhaps "regret" is the wrong word?  But I know, unfortunately, what regret feels like...and this is regret.  As I said...I don't constantly feel regret for my decision...but it is there...often.

Does this mean that I don't really have a desire to be a good person?  Does this mean that I'd rather make wrong decisions in my life to satisfy my immediate desires for happiness?  I think we all want that sometimes...more than sometimes...speaking for myself of course.  Instant gratification, well, I don't think I would call it instant...perhaps..."not eternal" gratification is what I often desire.

So what do I do with this regret?  I feel it and then move on and hope it goes away.  And have faith that there will be a day that I will rejoice in the right decision that I made.  I will know without any doubt whatsoever that it was the right decision and I will feel how right it was and regret will be something of which I will have zero concept.
