Eve I also know how you feel. I was taking my pre-recs (decided to go to med school after I finished up my bachelors), working 32+ hours a week at the hospital, also bartended about 15-20+ per week, and also had to be a husband and a father of three (soon to be four in another week!). Our two oldest are my wife's nieces that we are raising (they are 7 and 5). Our marriage has been rough.
What I found to be the best is assess your entire schedule for a week at a time. Look to see when you have free time, then you can pencil in extra things as you need to, like apps, family time, etc.
I did all my app stuff in the summer before, then filled out the secondary ones as they came in.
I got accepted to UHS for this fall, so we will see how things go this coming school year.
Never give up.....dont look at the big picture, just deal with the items at hand. And most importantly, find some time for yourself. I would go work out, or even my 30-min drive to work, was MY time! I could just relax and let my mind shut off for a bit (but still paying attention to the road).
If you want it bad enough, you will do it!!
