Whenever I failed out of college I decided not to tell my parents, my girlfriend or any of my friends.
Why didn't you tell your anyone about it?
My parents would be devastated and they would insist I go back to school.
It's not a crime to fail out of college. I understand it could be embarrassing but everyone is going to know about it anyway so you should have been honest with  your parents at least.
I know. Trust me it was difficult for me but I needed the experience.
Well now that you've made your peace with it, you should really tell your parents at the very least. They deserve to know that you don't want to go to college anymore, and that conversation will have to come at some point.
