Well then, do better and don't look back.

There is no shame in taking a first job out of college and realizing it wasn't meant to be.

Working at your age should be akin to dating...you should have no guilt or issue with realizing you acted without having complete information and perhaps jumped into something that wasn't, in the end, right for you.

Why not start actively shopping a resume and talking to colleagues your age to see where you could possibly land next?

Good luck, and keep moving towards a better tomorrow.
