Realized Im An Alcholic

I have been drinking since college .  I go out on the weekend and when I drink I black out pretty often.  There have been times where I quit drinking for weeks or months at a time.  This past weekend I hit an all time low where I passed out on the subway and this homeless guy had my phone where he called my mother non stop.  I currently live at home with my parents.  Have a part time job.  Used to be a teacher and have a masters degree.  My parents are kicking me out in a month.  Not sure what to do.  Thank you.
