The current answers seem good, but I wonder why you work? Or perhaps: why work so much?

You're pretty young and your parents are supporting you, at least providing housing, which is pretty nice. I'd tackle some of those personal projects you enjoy, and travel (at the very least, explore your own city), and learn to do some new stuff (learn Latin and read Cicero, practice a musical instrument, learn how to bind books, build a tube amplifier, other stuff we never have time to do 'cause working for rent/mortgage gets in the way). Go to the library (w/o a laptop) and sit and read, a lot.

I so wish I were young again...

And yeah, talk to your parents, being sure to let them do lots of the talking.
