firstly, I think it's really fantastic that you're being pre-emptive on any issues that might arise
I was married, in college and part of a stressful internship for the first couple years of my studies, it had some tough moments and there is a need for balance.
One thing that really helped me was to write everything down and adhere to a schedule. Make your priority list and then set blocks of time aside for those priorities and try to keep to the schedule. Staying organized time-wise is one way that I was able to enjoy life AND get the things done that i needed to do.
