There are many routes to keeping sobriety. 12 Step is one of them, and is quite effective for many. And it is the most available.
You have a desire to get and stay sober. That is the only requirement for a 12 Step program. Ypu can try it. If it still doesnt resonate, there are plenty of other secular groups, therapy, medical intervention, etc.
But do SOMETHING if you feel your sobriety is threatened.
