Stay at Home Mom.... Now?

Since my last post I have marked my spot in the land of "stay at home moms". Since Courtney was born 14 years ago I had always worked. I started my career as a Regional Sales Rep for a Medical Software Company about 5 years ago. I was successful and loved having that place in corporate america. I was making good money and balancing being a mom and career woman perfectly.... until 2 Friday's ago when I was let go.
I all the sudden was thrust into this new world of house-cleaning, job hunting, school volunteer work and of course boredom! For so long I thought it would be great to have the luxury of staying at home. But now that the kids are 14 and 11 there is no use for me here all day. I'm wondering if any of my readers have been thrown out into a new world of staying at home or even the opposite of having to go to work after having children? And what were the best ways to cope with this new crossroads in your life.
There are days I wake up and of course have a new business idea or want to be super mom... then there are the days where I feel utterly defeated and miss making a difference in a company somewhere. I was in sales and anyone who has ever been in sales knows that sometimes you have to be a shark. Well I miss being that shark. I miss the strength and confidence it gave me to be the intimidating shark.
There are no real opportunities to show the negotiation skills or playing hard ball at home when you are surrounded by 2 little girls and a loving boyfriend.
Was I faced with the fact that I no longer was the accomplished woman I had been in the past? Am I now the lunch making, laundry sorting mom? Talk about an identity changer.
