I can't focus

So much has been going on and I am struggling to focus right now.  My head is packed with what I have to do and what I haven't done and what I keep procrastinating in doing.  Yesterday and today I am struggling to figure out what to do and how to concentrate on it.  This morning I was driving to work and thinking of all that had to happen, all that has recently happened and I started to feel so overwhelmed.  I started getting really nauseous and tried to calm down and breath slowly.  Its not too good to be driving down city streets and thinking you are really close to throwing up.  I was able to make it to the parking lot and park the car before I did get sick.  Now in between bouts I was trying to look around and see if I was alone or if there were people pulling in or walking through.  I was so embarrassed but I had a few bouts before I was able to settle my stomach.  

i am going to try and plod my way through and find the path again.  I think I may be a little less productive than I like to be or maybe a lot less.  I am grateful for all the people I work with and the ability to bounce things around while I find my footing again.  i know it is with time that things settle all over again.  But if I can make a request, sooner than later please..
