Hey Cindi,
I know exactly how you feel. I wanted to go to college when I graduated from high school but I was prevented by my parents and guilt ridden by others.
Three years ago I found myself in a divorce...I knew I had to do something for my two children. At the time it was only for my kids but I'm ending my first degree and I'm getting ready to enter my second; the degrees are more for me and not only my children now.
One psychologist told me, "if you look in the rear view mirror you're gonna crash but if you look straight ahead you're gonna get where you want to get". He is absolutely right. Don't look in the past (or the rear view mirror) look straight ahead to what you can do and you'll be so proud of yourself.
Good luck and hang in there, I know it's tough (from experience).
