Stay at home mom (41) thinking about going to school, is it to late?

I'm a 41 year stay at home mom. I have 3 grown kids and a 14 month old at home. My husband and I recently split due to his alcoholism and I have no education or job. I can go back to my old job prior to having the baby, however, I was considering going to school and making something of myself vs working making little pay. Is it worth going at 41? The program I am interested in is a 2 year program for radiology but is someone going to want to hire a 43 going 44 year old woman who JUST graduated school? I'm torn.
