I know the feeling. When my doctor ordered tests to check out my liver, I was scared to death. I did what you did, and did some research on google. Big mistake. I thought for sure my life was over. Turned out I was fine, but the fear I carried with me until the results came in was a real eye-opener. It's amazing how fast the body can heal once we take a stand and made changes in our lifestyle.
Also, I can relate to your situation with your mother. My mother lived with me for several years. One day, she told me she could not take my drinking anymore and got her own place. It happened a long time ago, but I can see that moment like it was yesterday. Eventually we worked everything out, but that moment will haunt me forever.
Sounds like you have good reasons to quit drinking!! John
