PMHNP Online Program Time Commitment?

I am an older student (47) planning to return next semester for my Psych NP at University of Southern Indiana. I have a good and well paying RN job in California, but I want a new challenge in the next 20 years of my career. I am concerned because I will still be working (can cut down to half time as needed) and I have adolescent daughters who are pretty demanding of time and energy right now. I'm questioning whether I'm biting off too much... Anyone on here that has done a part time Psych NP (program is online, although obviously clinicals will not be) program, how did it go for you? How many hours per week on average were you doing class/studying? Are you happy with your career path? Anyone happen to have done the program at USI? Spinning a bit, so would love to hear from others. Thank you!
