Winding the clock back is one of those things we all would like but it can't be done. We did what we did and the only question of importance is what are we going to do about it? Likewise with alcoholism, we can't go back to normal drinking - ever without disastrous consequences. You can't turn a pickle back into a cucumber as they say.
So maybe it is in order to caring a few blessings. You have a terminal illness that will not only kill you, but will kill all your relationships, family, and will cost you your job, business, self respect, you name it, and it will end in permanent insanity, locked up, or covered up in a miserable lonely alcoholic death. That's the prognosis.
Instead you have a family that loves you, friends who are still with you, and people who care around you. Sure they are worried you have a drinking problem. Who wouldn't be concerned given the prognosis? But what a wonderful thing they are trying to help you stop. I read post after post on this site about the trouble people have with friends and relatives trying to make them drink again.
You seem to be blessed with a wonderful family and friends, and all you have to do to keep them and save your life is stop drinking. Sounds simple, and it is, but it is not easy. Thankfully there is plenty of help available. I pray you will make the most of this opportunty.
