Just When You Get Comfortable

So today was not a normal Tuesday for me at work. I thought I would come in and doing my monthly reports and then my regular daily work. Then around 10:00 am my manager comes to me and asks for me to come to her office she needs to talk to me. I was thinking "great what have I done now" I figure it was cause I don't follow dress code and I am always taking my shoes off and not wearing socks. I was totally prepared to have to start wearing socks. So I sit down and she looks at me and says "I have put in my resignation. My last day will be October 2nd." I just looked at her in shock. I wasn't quite sure what to say. I started crying and told her she wasn't allowed to leave. I am just so heart broken and lost. I am not sure what is to come of our department and my position. I really liked her and vs versa. It just goes to show that you shouldn't get too comfortable with a situation cause in the blink of an eye it could change. We have a meeting with the vice president to tell us what changes will be made and what will happen in the future. I am so scared to find out. We shall see.
