Panic

I can honestly say that since Big Miss left for college in August, I haven't worried all that much (surprised?) until this past Thursday.  She was driving home from her new job and got a little lost, so she called me.  This is the hardest part of kids going away to college, they call you thinking you are going to help them and while you are acting strong, you are slowly dying inside.  I told her to use her GPS and call me when she got home.  I was at work, so I forgot about it and continued on with my day.
At 9 pm, hubby asks if I heard from her today because he texted her and hadn't heard back.  Instant. Heart. Pounding. Fear. Ensued.
I call, no answer... I text, no answer... I start wondering how I will get the news: do they call the local police to come to your house, am I going to hear from one of her new friends that I don't know, is a stranger going to find her phone and call me... you get the picture.
I remembered that I had her friend's number, so I texted her and it took 30 minutes to hear back from her that my Big Miss was sleeping!!!!! I then get a text from Big Miss saying "sorry, I knocked out when I got home" and that was it.
The next day when we spoke, she told me that I need to chill out and relax.  Does she not remember the crazy person who dropped her off in August and cried for weeks?  How can she forget the person who watched the clock her senior year and would twinge when her curfew came and went (even though she never came home more than 15 minutes late)?
I am seriously thinking about getting medicine for my anxiety about this whole college thing.  BECAUSE Little Miss has also decided that she too will leave the nest!!!!!
