Seems stupid, because I've spent all this time and money on getting a degree and for the moment I don't want to use it. I just want some time for myself - my own time that I don't owe anyone else for a little while. Whatever.

Not stupid--very, very smart! Take some time to catch your breath and figure out what you want to do. It's unwise to rush into new, high-pressure craziness right after graduation. You have a job and stuff, so just make some money and relax! You've earned it.
