Sorry you're feeling lost right now. I think the right thing to do is to give her the space she needs. Maybe she'll come back to you, maybe she won't. But it's good to know she was in your life for awhile and was able to inspire you to give up a bad habbit. At least she knows you care for her.

How long has it been since you had that conversation with her?

Stay strong, and please don't fall back to your old habbit while things get sorted out.
