How do I start?

Long story short I been a heavy drinker since 16, I’m now coming up 29. In the past 2 years life has got me down bad now as of last July till now I have been drinking heavily every day. I’m not talking a crate of beer I’m talking to blackout daily. If I wake up and there is no alcohol in the house I feel anxious. It’s getting rediculous now I been the doctors and was offered practically nothing. Everything surround booze, it’s all I think about and unless it involves getting shitfaced I don’t want to know. I just want to go back to not drinking at all but then on a Saturday taking it way too far, without downing 2 cans and a shot Sunday morning. I want my life back to normal this just ain’t it 😭
