Alcoholic who is tanking

As with most addicts/alcoholics, I believe my last is my last, and so I have conned myself into believing that I could certainly kick my habit before it fucks me academically. I have missed most of the semester, and I just missed all my midterms. Outside of college, health wise the situation is also getting dicey. What should I do? Losing around 6k sucks, tanking my gpa sucks, life sucks. I should obviously get help with my problem, but is there anything I can do to soften the landing academically?
