I totally understand how you feel. I'm sure her heart IS in the right place, but I would feel the same way you do.
Maybe you could just tell her that you prefer to make your own plans about meetings, and that although you appreciate her keeping in touch with you, you already have plenty of phone numbers to call if you need support between meetings.
Hopefully she will take the hint and back off. If not, it's really her problem, not yours. As plenty of people around here will tell you, "90 meetings in 90 days" is NOT "working the program". I did it, I think it helped me, but there's nothing magic about it. If you get a sponsor you can work with, that's the best way to do it.
Good luck, don't let her clumsy attempts at "helping" throw you off track.
