I left my husband when I was 38, moved to Atlanta and had a wonderful job at the merchandise mart, managing a showroom. (My kids moved with me.) Unfortunately the company closed, I lost the job and my next few jobs did not pay well. After two years of struggling to pay my bills, my husband divorced me and my children went to live with their father. (Too long a story to tell here.) I knew there was no future for me over there, so I sold what I could and moved to California and began again; I was 40. It was plenty scary at times, and if it weren't for friends I would have starved, or had nowhere to sleep. But though the first two years here were hard and I had to work more than one job, I learned how to take care of myself. I also learned how to save money so that the kids could visit me for the summer, because of course their father would not pay for that.
Year three I found a good job with a law firm and was finally making enough money to get my own apartment and so in year four my kids came back to live with me.
What I'm trying to say is that when it's time to make a change, figure it out and make the change. You can do it, have faith in yourself!
