Mom guilt

I was just accepted into a highly competitive accelerated BSN program. I really thought I wouldn’t get in and now I’m finding that I’m not as excited as I thought I would be. I have a 15 month old that I stay home with much of the week, I’m currently only working 3 days a week. The program starts in August and it’s an hour commute from where we live. The schedule for the first half of the first semester isn’t bad, but clinicals pick up the second half so I will have class 2 days a week then 12hr clinicals 3 days a week. I’m already feeling guilty about the time I won’t be getting to spend with him. I’m 30 and I know nursing school is challenging but I was hoping to get some insight from moms that have been in my shoes.
