I am attending a direct entry, accelerated NP program. I am 38 and the single mom of a 2.5 yr old with no support from her dad either. I have set some boundaries for myself so I can be both mom and student. I will be in this program for 3 years so I can't just suck it up for one year, I have to pace myself.
I'll share what I've been doing, You can take it as it is....advice from another overwhelmed mom. But maybe some of it will be useful for you.
Let go of the A's. I actually fist pumped and did a little dance for my B+ in pathophysiology. I carried 20 credits of coursework this summer alone. My brain hurts most of the time. I study and go to classes like it's a 40 hour a week job while my daughter is in daycare. Occasionally, I would find someone to spend an afternoon with my kiddo if I had a big test coming up.
Get sleep. Don't cut it too short too many nights in a row. Lack of sleep makes you slow and less-productive. I need to be as focused as possible when I am studying so I get the most out of it.
Use study groups! If you can find the time to get to one. Try and start one in some down time between classes, even 45 minutes helps. If you can't get together in a group, share study guides on google docs. This has been a HUGE help for me.
Eat. Even try to eat well.
Use Kid time as a stress reliever. Chase them at the park. Climb to the top of the slide and giggle on the way down. I let Ruby eat ice cream with abandon. Being completely in the moment with Ruby makes her less angry with me when I am studying and I don't have some ugly mantra running through my head telling me I'm a bad mother for neglecting my kid. I try to avoid studying while she's with me and awake. We are both happier when I do this and my grades have not suffered.
Ask for help. From anyone who has offered help in passing. Afternoon play dates, Babysitting if your sick. I don't have a large support system...not really any family around and her dad is not able to contribute to childcare or much of anything else. So I'm creating a system. People have been amazing and I've found support from the least likely places (like my auto mechanic).
Make friends with other students. Even the students that are young and untethered have been supportive. They often get together for study groups or social events but I am not able to go. Instead of being envious or feeling trapped, I reframe it to be happy and supportive of them for having fun at this point in their lives. I remember being in my 20's. I hope they have nearly as much fun as I did!
It's hard. Cut yourself some slack. Keeping your type A personality in check will help you out in the long run
