Damn man, I feel for ya. And I'm assuming money's a little tight too, otherwise you'd be out on your own by now? I'm in practically the same boat, only my mother isn't some schizo who might have a drug problem of her own?

Seriously, is she on anything, or possibly chemically imbalanced? I ask that because the way you described it, her writing off her whole family sounds a little erratic and out of the blue.

Hopefully you're trying to get ahold of any or all of your friends to look for a temporary place to crash, because you walking around all day is just no good man.

If you have enough cash to maybe rent a cheap place for the time being, DO IT. Like even a cheap hotel room until you get a job and the money comes flowin' back. Just an idea. I think I would be out of there anyways. OR you could call the cops her on for doin' God knows what, because she sounds either mentally ill or on drugs.

Hope things get better. ~
