How do I apologize?

I need to apologize to someone for saying (writing) something wrong, but I don't have any way to contact this person, so I'm putting it here.  (If it's you, I think you'll know.) I wrote something in response to something, having my heart in the right place but my words not so much.  Fortunately, the person did not publish it, and for that I am thankful. 

I didn't think it through carefully enough.  That was a mistake.  I was writing with my emotions and not thinking about how the comment would come across.  I just want to say that I'm sorry if it hurt you or made things harder for you.  That was never my intention and I have wished that I could email you to say it more personally.  I hope that things are all right and that you are doing okay.  I hope that you understand what my intentions were (although we all know where that road goes.  Right, the one paved with those good intentions?) and that I did not mean to sound callous or to be rude in any way. 


To all of you, I am certainly not perfect and I know I mess up sometimes.  I try to be a nice person as much as I can and I know in my personal life I fail miserably sometimes!  It's hard to admit I did something wrong, and harder when I can't say it right to the person who needs to hear it. But to me, it's even worse sitting around thinking about the thing I messed up, even when it wasn't intentional.  So as unpleasant as it is to apologize publicly (sort of) and admit that I made a mistake (because I HATE making mistakes), I know that this is the right thing.  And no, not just so I will feel better, because to be honest, I won't, and that's okay.  Because it's not about my feelings right now.


So again, I am so sorry I messed up.
