Aysha, You don't need any 12 step program to help others, although in helping others you're doing the 12th step. 74 years ago Bill Wilson and Dr Bob Smith discovered that the only way they could stay sober was by helping others achieve sobriety. Out of that epiphany came AA, yet at the time they had no steps to follow, no program to work. They just did the best they could buy giving others the help they needed.
So I suggest you follow their footsteps. This isn't to say join AA, but rather look at what you can do for others. This site attracts people looking for help and advice. You can tell them what worked for you, how you did it. Outside of this site you'll find ways to help others, believe me. And I'm certain that in the days to come you're going to get a lot of suggestions.
