Dogs, Days, & Possible Depression?

You may not be aware but I moderate the comments that come through this blog. I moderate mainly because I  do not want any profane items showing up.
  That being said, yesterday I had comments to moderate for my previous blog "Today's gonna be a great day". I opened the comments and was unsure of how to respond or if I should.  The comment left was:
"Every dog has it's day", and this bothered me. I've thought quite a bit about my reaction and others if they had read them.  My Prednisone fogged brain immediately saw the negative. Thoughts that ran through my head were: What! Are you jealous?, How dare you?. The more I thought about it, the more I wanted to contact the person leaving the comments and ask if they would explain why they would leave such a comment.
     I've discussed this with a good friend and his response was the positive side. Yeah every dog has his day and you finally get to enjoy yours! I somewhat agreed, but why post it that way? Congratulations of a Gift of Life would sound more apporpriate.  During our discussion I had the epiphany that possibly this person was depressed, maybe waiting for a transplant. I explained my reasoning as this person was reaching out for a shoulder or someone to listen and say, I've been there too. Thus the true meaning behind my blog.
     First let me remind everyone reading, that the sole purpose of my blog is outreach. To  help the healthy understand what we endure in our quest for survival , but more importantly to be there for those candidates and recipients who need to hear it's ok to feel this way.  Please don't misunderstand  that because I sound positive now, this does not mean it's been a perfect day at the beach the last 20 years of my life.
It has not, by no means.  But and I state this emphatically, I have been there, I have conquered whatever  the medical field has managed to throw at me, and I am still positive and ready to tell everyone about it.
     So I would like to close by letting this person know that even though you left the comments, I hope you can let me know you are OK. More importantly if you need someone to listen while you let all the anguish out, I am here. If not me, I will happily put you in touch with others like me who care.
