Hi Mixie;
Sounds like both of you have communicated to each other (at different levels of skillfulness) what amount of contact you are up for.
You'd like to be in contact, and are open to working with her and a therapist to make that happen.
She is telegraphing that she does not want to be in contact and isn't engaging with emails or phone calls.
It seems like you've been clear about what you're up for -- she knows -- and she's also communicating (though less clearly/explicitly) what she's up for. And you two are in pretty different places right now.
You might be on to something here:
I am no longer the one who is being called with crises, which is a nice change. Maybe it is her awkward way of cutting the apron strings...
She might be maturing into adulthood in a low-skill way, with lots of bumps on the road... but she's doing it. It's normal for children to at first need their parents to help with crises, and then, as they get older, not to need that kind of support any more. She may not be doing it gracefully or kindly, but... she's launching -- she isn't inappropriately relying on you to solve her problems for her.
That doesn't mean it doesn't hurt; it would be so nice if she could communicate in a thoughtful, skillful way: "Hey mom -- I'm going to take some time for me over the next year or so, and take a break from touching base with you. It's just time for me to make my way in the world. I'm open to reconnecting sometime, I just don't know when that is right now. Thanks for offering the counseling, even though I'm not able to take you up on that."
Maybe that's behind everything... I would hope, for you.
