Just went to college, worked part time, did weekend mgt of my old apartment complex, and made ends meet. It was the hardest 12 years of my life. In hindsight, I don't know how I managed, but I did.
You will too -- it's difficult but builds you into a person able to handle anything. It's kinda funny -- my everyday life seems so simple compared to the work I do.
I guess you get conditioned and develop due to the beatdown :)
