Sacrificing now will pay later... right?

Since graduating from college, I immediately started a nursing school full time and a part-time job in order to pay for the extremely expensive school. In that time, none of my friends in Richmond have done a damn thing except spend money frivolously, vacation, and hang out together. While I'm doing homework, they are at concerts. While I'm making money, they're playing tennis. Because of this, I have the sense that I'm becoming less important to my core group of friends because our priorities are entirely different. I know that I'm in debt to pay for the school that is necessary to have a lifetime essentially free of financial stresses, but I wish I was in the same boat as everyone else I know.

Because this little boat sure is lonely.
