COMPLETELY agree with those here that think your current doctor is being "ridiculous". I don't recall it being a good idea to pour gasoline onto a blazing fire. I just don't get it. Please do seek a second opinion.
Sweetheart...you have 5 kids that NEED you. I have 4 of my own and you cannot imagine how happy they are now that I am sober. I think I honestly lost sight of that while I was drinking..... my value and importance . But I KNOW it now.... People will tell you to give up using ( or in my case, drinking) for yourself....and that is fantastic, solid advice.....but for me personally to really quit drinking, I had to first give it up for my family. I made a promise to them..... quitting for "myself" came later on. I hope you will do the same. You won't regret it.
