Drinking is big fun.
Until it isn't.
Once it isn't, it never will be again.
Addiction is using in the face of increasingly negative consequences. Trips to the ER and medical detox to avoid DTs are clearly negative consequences. You've clearly crossed a line, and will never be able to drink non-addictively. Period.
You are 25 and have two choices. Spend the next 10+ years of your life going in and out of alcoholism, wasting your time, your life, and the lives of anyone close to you, damaging your health, until you finally reach a point where you have to quit to avoid jail, homelessness or death.
Or you can quit now and continue living a real life.
If you keep drinking, the next ten years will not be sad. They will be tragic. You may view sober as sad, but even if true (if you do it right, it isn't btw), your alternative is horrible.
Choice is yours.
