Do You Believe in Signs??

I have been driving myself CRAZY lately obsessing over my decision to become a nurse. I have my interview on the 19th for their program, as you know, and I have nothing else to do at work than to obsess about this decision.
So I was reading up on different areas of nursing and am interested in Forensic Nursing. I was reading up about that yesterday. When I was riding the shuttle bus from work to my parking yesterday afternoon, I was looking out the window and what did I see but an SUV drive by with "Forensic Nursing Response Vehicle" printed on the side of it. Have I EVER seen one of these before in my life? NO! This could be taken as a sign, could it not?? Seriously, I have never seen this before ever. I am sooooooo tired of obsessing and sooooo tired of being so unmotivated at work.
I do not know how much longer I can last...
