Time Management

I'm having an issue and it's day 4 of the semester. I'm taking 17 credits. 17, for the most part, very involved credits. Genetics, human embryology, cultural history of medicinal plants, physics, intro to food prep, molecular bio lab and cell bio. It's rough. I come home from school and I do more school. I read, and read, and read. I feel like it's doable, and I feel like it would be even more doable if I didn't also have a job, a need to eat, and a desire to have a social life.

I have this issue where I think that it is really important to be a good friend. And to have a break from the intense comprehension of my reading assignments. So I find myself scheduling in all these people around me and taking breaks just to spend time with people that I truly love and who help me stay sane.

How do I balance school, work, church and a social life? This is difficult.
