SR has been PRICELESS in my recovery; it was here that I found the support I needed.I never did face to face meetings, either.
I did have several very supportive friends, a couple of whom had addicts in their own lives and were able to give me reality checks when I started wavering from my path. I saw a counselor for a while and met with my pastor several times. I read A LOT, too.
I think you do whatever is right for you; maybe encouraging your mom to get some support other than you would be a good idea? Not that you shouldn't help her, but it is very easy to get consumed by addiction. It was my husband, not my child, that is the addict. My heart just breaks for all the parents here.
