So, this is bad but I was just lazy for 6 years of my life.
That's hard to admit. Did you not want to find a job?
I was too lazy to work
It's important to get a job and not be so lazy all of the time.  Your life will be much more rewarding if you work hard some of the time, and relax at other times.
So I should be working a shitty job and doing 5 classes, while living in a shitty house, with all of my money spent on my stupid family who will never appreciate me.
It sounds like you are suffering from some depression side effects. Not having any motivation, feeling like there's no point to anything, those are all signs of depression and it can get serious. Have you considered talking to someone?
