My "Why"

I need some help with my homework if ya'll don't mind!
Please read all of this post and give me your honest opinion.
I have been asked how I learned about My Power Mall, my answer was, I read about it on a forum and people were talking about the hassle of Christmas shopping, someone mentioned why don't you get your own shopping mall, I wrote the name down and then forgot about it until Christmas, when I was standing in the dreaded long line to check out. Needless to say I checked it out when I finally got home, liked what I saw and got my own mall. Little did I know it was so much more than just a shopping mall, these people actually wanted to HELP people, imagine that?
The next question was, why do I want to help others? What is My "Why"?
I will just tell you a small part of my story and hopefully ya'll can steer me in the right direction.
I am an ex-alcoholic, have been for almost 4 years now and I thank God every day for my freedom. I come from alcoholic parents. Almost every problem that my family has had was alcohol or drug related. My brother died in his 50's from a drug overdose. My grandson is on his third round with crack addiction (that I know of) and I expect he will be back in jail soon if he isn't already, he has a 1 year old that needs him. I never really knew my father sober, but he was a fantastic father, never abusive, he helped so many people, I love him dearly, he just never got over ww11 and the people he had to kill to protect our country.
My sister is a Special Ed teacher, almost every one of her students are handicapped in some way due to their parents drug/alcohol addiction and most of their parents are incarcerated leaving them to be raised by their grandparents or foster homes. I could go on telling of so many lives that have been destroyed of just the people I know, but you get the idea.
I voluntarily went through rehab for a year, also AA. I have watched my grandson go to several rehab programs obviously without success, my brother went through a bunch and I will say this, my going through rehab did not heal me of my alcoholism, my faith in God did. I DO NOT believe that once you are an alcoholic/drug addict you always will be, but my doctor tells me so, rehab tells me so, AA tells me so, that's a bunch of horse hockey!!!!! Why are they setting people up to fail in this by telling them that crap?
For those that would say "she must not have been a very bad alcoholic", in 1999 my family rushed me to the hospital, I was neon yellow, with no insurance, the doctors told my family to take me home and if I lived through the night they would be surprised, well I lived obviously, and stayed sober for almost a year. Why I went back to drinking, I will never know, but I did it with a vengeance, I'm talking 24-7. I realize now that I am still alive for a reason. I want to help others with their addictions, I just simply don't know where to start. Any programs that I have found that may help are too expensive for that person who has lost everything due to their addiction. Thanks for listening, any advise is most welcome.
