Interesting. Pretty much my story. I have found in recovery though, that it a mistake to get hung up on sub types and differences. I sobered up when I was 22 with the help of many older members of AA.
We had exactly the same disease, and the solution worked exactly the same for me as it did for the older folks. I had contemporaries who were really hung up on being different. Most of them didn't make it.
AAs solution to alcoholism incorporates the wisdom of ages, and much wisdom from older members merely through their life experience. Generally speaking, the young, even the sober young, are not usually fonts of wisdom. We still have to aquire it over time, just like everybody else.
