Hi lesa,
I attend AA but have been went to some NA meetings when I first got sober. I personally feel like I belong in AA, but NA is just as wonderful a program as AA. That person that said NA is negative - that is their opinion. I was told in rehab to grow where I'm planted. For me, that is AA, but someone else, that may be NA. I know a lot of people that attend both fellowship also. Totally a personal choice.
