You have to be willing to do whatever it takes to stop drinking. You obviously feel miserable, you have already experienced losses because of it, drinking is destroying your life.
There is a way out of this. It's tried and proven by many many here - you give up this one thing to have everything. Otherwise, eventually you give up everything else to have this one thing.
Commit to sobriety, seek help, and your actions will speak louder than anything else you can tell your friend.
