I know how you feel. I missed countless hours with my kids while I was in school, studying for the FE, then the PE. I love my children unconditionally, but that doesn't mean that they haven't create obstacles and I don't think there's anything wrong with admitting that. I remember interviewing for a scholarship two days after delivering my second child, pumping in the bathroom between classes, taking my kids to class with me when their schools were closed but mine wasn't. Going through this process with kids is challenging. There's definitely a work/study/family balance and it's hard on all parties involved, but the benefit far outweighs the cost or we wouldn't be putting ourselves and our families through this right now.
I am looking forward to giving myself back to my kids; physically, mentally, and emotionally; as are you and many others on this discussion board. I wish you the best of luck!
