Leaving for awhile...ambivalance...help

I think am going to be leaving nursing for awhile to pursue other career interests as well as fullfill family needs. I have two children who will be in K-5 in the fall, and my husband and I decided it would be great for me to be able to be home with the children this fall and to volunteer at the school they attend.

So now that he has agreed with me, and everything is set for me to quit my school nurse job with the end of this school year in mid June I'm wierded out. I was so excited all year knowing it was the last year for me, but now that I have the contract in my hand for '08-'09...I'm not sure. I want to be home, I know that part. I'm excited to work less and be with my children more.

The problem I'm wresting with is ambivalence. My husband and I met in college while were both already pursuing degrees/diplomas. Our reasons for pursing such accolades were different, which we did not figure out until after we were married with kids. Assumptions....

I pursued nursing first and foremost as a way to support myself anf my child I had at a young age. My now husband chose his career becasue he has a guinuine love and interest in his chosen field even to this day. It is a hobby for him to go to work.

It changed my perpective about careers and employment after comparing the way he felt and the way I felt about a work day. I started taking classes toward something I have found to love, floral design.

So now everything is set, we're financially ready for the difference in pay, he's set to have a wife who's at home/working part time at something new, but I'm freaking out....I never expected to be wishy-washy about what it would be like to quit my identity that I've had the last 10 years...

Anybody else going through/ has been through, the what if's...?
