Well first of all don't quit alcohol cold turkey. That will possibly kill you especially since you have been drinking for a very long time. I would suggest lowering the amount you drink if you drink half a bottle daily lower to maybe a shot a day for a while then to maybe a beer then quiting and going sober. Maybe find a group to help you on your journey to sobriety. It is very hard to go alone when quiting an addiction. There are support groups out there if you do go into alcoholics anonymous be careful they can be fairly religious centered if your not extraordinarily religious there are other groups than can help. Possibly look on Reddit. I believe there a few groups out here that help with addiction. Also maybe change the environment you are in if you can't quit and try the above and surround yourself with people who will push you to drink. Just remember this is ultimately your battle and yours alone. Others can help but,you have to do the work.
