Welcom Whacky!! So glad you found SR.
I can reallly relate to your story as so many others will too. My drinking really took off while at college also and it continued for many years after that. The depression and anxiety were awful. I too had a great childhood, but somewhere along the line I found alcohol and drugs and I was off and running.
The good news is that you don't have to live like this anymore. You will find so much support here. Read and post often. You'll find that you are not alone in how you feel.
Best wishes.
God bless.
