Is it normal that i'm going back to community college after a bs

I'm curious to know how many people out there are going/have gone back to community college to get a skill after finding their 4 year university degree to be more worthless than a poopy flavored lollipop? I majored in physics and not soul in the world wants to hire me. Community College is a cheaper alternative for finding work than graduate school. I suppose anyone who's been through this understands the regret and depression that after paying so much into something, that you are still considered to be as worthless as you were after graduating high school.
