Concerns about 12 step

I'm going to get involved with a local SA group to aid recovery. However I have some concerns about the 12 step program.

I don't like the disease model. The idea that we are powerless in the face of the disease and must manage it and keep it at bay for life. I don't like the idea of for ever labelling yourself as an addict and approaching recovery from this place of weakness.

I'm not down with the higher power idea. Again it seems like abdicating responsibility and putting yourself in a place of weakness instead of strength.

I don't know too much about the 12 step program, so maybe I'm off base and my concerns are unfounded. I would appreciate some feedback from those with some experience.

thanks.
