Did you attend NA meetings for yourself, or for someone else? If you want to quit, that's better motivation than someone else asking you to quit (usually). Is the NA format (12 steps) not something that appeals to you, or the group dynamics?

The program is built on including a "sponsor" as a support person while you're going through the program/steps, but you don't necessarily need to do it that way.

Perhaps you could look into getting a substance-abuse counsellor instead?
