HELP!!!

I am unable to get my text to a medial alignment! I did widen my margins for the blog, but other than that, nothing that should interfere...When I am typing (like now), I highlight for the text to be central, and it shows on the toolbar, but won't appear that way during typing. I thought maybe it would just be on the composition page but show up as intended on the preview or final publish. It's a no-go.
What is happening???

My back really, really hurts. It has been very unfun at the office this week. And I would rather like to just complain.
But in doing so, I am not acknowledging to my Creator all that's good in my life. Even the yuck-I know that as much as I may think otherwise in these moments, it is while dealing with life's difficulties that I begin to grow and become stronger. These are the thoughts I had last night as I was driving home. Alone. In peace and quiet. For 90 miles. And facing one of the most beautiful sunsets ever.

I started the draft for this post last week. Didn't finish.
We had a busy weekend helping someone demo renovate a project. In a town 90 miles away. Got stuck there when a blizzard came through. Spent an unexpected night in a hotel. Still took double the usual time to get home the next day.
My back still really, really hurts.
My doctor and I had a nice visit this morning. And thus, the pharmacist and I shall see each other shortly.
