Change jobs!!! - Even try to get one where you can do some or all of your work at home. That is what I did. After leaving my husband I raised my three children on my own and despite working full time always managed to be there when they were at home and when they needed me. It isn't easy but it can be done! Look at the kind of jobs that will enable this and retrain if need be. You are first and foremost a mother and way after that you can be an employee. Good luck!
