What Is Rock Bottom?

Is it the feeling of having no place in high school?
Is it the unquenchable depression of having nothing to show for 4 years of high school?
Is it the knowledge of a coming report card full of F's?
Is it the hopelessness of being unable to get on a track that makes your parents proud?
That no matter what career you choose there will be many lonely years ahead until it is established?
Or maybe it's finding a place where making money comes naturally, only to squander it on an ill advised dream?

No today rock bottom is putting in months of hard work only to have all the painstakingly earned money spent on something as trivial as a place to sleep.
