How do I start this out???

I have had a very busy day with everything that has been going on today. I started out my day with running late to go drive the school bus this morning. Then I had to meet my mom at the school with my daughter because it was "Grandparents Day". I met with them and took both my children to the book fair and bought them some books. My oldest child is in the 1st grade, please pray for me... So far right now everything is going ok, most of the time. She has came home with some marks on her behavior chart a few days, but has been doing better at school. But when she comes home, that is a total different story. I talked to her teacher today and she told me that everything is going good with Shelby, that it will just take some work. She is not wanting to learn her sight words, at home. As of right now, I am so fed up with trying to help her that it is an ongoing battle that I am losing. I also have a 3 year old that is so interested in learning everything that she possibly can and it drives Shelby crazy when she watches and wants to know what she is doing. I understand where Shelby is coming from when she wants Haylee to leave her alone, but then again it is easier to teach the same thing to two children instead of teaching it two times. I am slowly working on my patience. I am working on getting certified so I can sub at the Elementary school and I am also thinking about changing my degree to Education. I can deal with other children better than my own, it is like my own children know how far they can push me and push as far as they possibly can before I explode.
But anyways, back to my day. I had to go for a MRI today. This was the first MRI that I have had since I was 7 years old. The MRI that I had when I was 7 was awful, I screamed and cried. This time, I was nervous as hell. I went in there with the idea of something completely different than what happened. I was lucky and got the open MRI. I think it went fairly well, I could have fell asleep if there wasn't so much noise. I am hoping that they can find something out with my neck and I hope that it is not anything too bad. I am on so many different meds right now and I hate taking meds. It was a fast and painless procedure, those I can deal with.
I then came home and had to get ready to drive the school bus this afternoon. I was really dreading driving the bus because it was so HOT outside. But I got on the bus and got to the school and visited with some teachers. Then the bell rang, all the children come running out to the bus. They were louder than normal and I could tell this was going to be a rough afternoon. Well the high school students got on the bus and were extremely loud also. My route is the longest route at Vincent, it runs into Vandiver and Sterrett. Almost every afternoon, we have to sit at the RR tracks for longer than we should because the students do not want to shut their mouths long enough for me to listen for a train. Well today was the longest that we have ever had to sit this year. They were so bad that an Kindergarten student stood up and told them to BE QUIET, RR TRACKS! That is bad when a Kindergarten knows the rules better than a high school student. Well the route was going ok, just really loud. Then all of a sudden I run into rain, thunder and lightening. I actually went towards a funnel cloud, or at least that is what I thought it was. I rushed the kids off the bus and went on my way. I did not want to stick around there and see what it was. I finished my route and came my butt home before I had to deal with anymore bad weather in a bus.
Now I am home with two children that do not want to get along and dont want to listen to anything I am saying. So as I close this, please pray for me and my children because I really don't know what this night will bring. My hubby is on his way home, so he can take over when he gets home.
