Getting blackout drunk every time I drink

So I got on probation like a year and half ago and I’m 18 now. I was smoking like 8 times a day. Ever since, I’ve drank every Friday and Saturday and first off it started slow. Like I would have a little bit to drink every Friday and Saturday just to feel good. But ever since like the 6 month mark I’ve drank until I’m blackout. Every time I drink I get blackout and can’t control it and don’t remeber anything. I drink so fast I’m blackout within an hour of drinking and I can’t stop it I just don’t want to feel anything and I do so much stupid shit while blackout drunk y’all don’t want to know. And it’s getting worse. I should be off probation next week but I feel like I have an addiction now can any of y’all help with this?
