How should I talk to my mom?

To start off my rather long story (feel free to skip), I have depression. I had depression for many years now, and it was only until about a year and a half ago that I was given the chance to go to counseling, something I am grateful for. And my dad is great to talk to when I'm not in counseling. It makes me feel good that I have him to vent to, and that he actually knows what to say to me to make me feel better. Although as for my mom...
She is kind of the opposite. Instead of trying to vent to her, she turns around and vents to you. And believe me, I listen. Although I feel like she doesn't listen to me. And if I try to tell her that it doesn't make me feel any better when she says a certain thing, she doesn't seem to care.
The thing though that makes me upset is that she seems confused of why I don't talk to her, or why I don't rely on her for help. And when I tell her why, she doesn't fix what she did wrong. She just argues back again that she is right in this situation, and that she doesn't care.
So my question is this. How do I make her see that what she says does not help? And would it be too bold to show her a site called, "what not to say to a depressed person?"
