Oh Sugarre,
I am so sorry.
If I can relate from my experience, my guess is your daughter's emotional circuits were overwhelmed by all you were going through, and the divorce on top of it was just too much. It's a wound, and though she DOES love you, right now talking to you triggers emotion she can't handle. It's not your fault. You did the best you could at the time and she knows that. I would bet my boots she will find her strength and grow up some more, and then will be able to ease into a new adult relationship with you.
But I do know so well how very painful it is when they do that...isolating, cutting you off. It is horrible. I am very sorry you have that to endure. I hope that enduring it for a time is all that is needed. I am very glad she wrote you and assured you of her love.
I just called my daughter at her work to tell her her grandmother's ill. I just said to her, without sounding too angry...I would really appreciate it if you would return my calls. She is nice but defensive, oh I am just so busy and I was planning to call you today or tomorrow...I'm fine just swamped. So I told her, hon, you really do not have to have big conversations with me when you're not up for it. But a five-second voicemail that just says, I'm fine, or busy, or whatever, is all I'm asking.
I know sometimes talking with me has been traumatic for her because we are very close and I too have had my cycles of anxiety and depression...sometimes I have just overloaded her. Or, we'd trigger each other. She has her own emotional perils and she can't take mine on. Can't handle my pain on top of her own. (Shouldn't have to, either.) So she isolates. And then when she does that (won't call back, etc.)--I feel worried and after a while, resentful.
But when we reconnect she is 90% wonderful. She can be very loving and giving. I don't know what paralyses her from communicating sometimes, but if I just wait it out she usually comes through lovingly. Alone in the dark, and when I'm feeling alone with the burden of my mother, I get paranoid that my daughter's an N. But I don't think so...it's just that although I don't do it any more, for too many years I made her my friend instead of my child. And that's just too heavy a burden for a kid.
I'm not an objective judge of these things so I don't know if this is good advice, but I feel it's okay for a kid to learn that a few obligatory check-in calls, particularly if the parent does not do an emotional melt-down and demonstrates "I am not asking you to take care of me" in their tone of voice... anyway, I think it's good for a young person to learn that their parents are still learning and evolving too. And that if the parent isn't throwing their whole mental health in the lap of the child, then it's okay for a child to learn there IS some obligation to be in touch now and then. I think so anyway. So, if you do know where she works or lives, and could leave a message in that sort of tone, I'd do it. Or if you have an address to write to, and can keep it very calm and to the point, then that would be worth doing too.
Maybe something like, "I do not want to call you at work, but I do need to know you're okay. So if I don't hear from you by ___, then I'll call your workplace just to be sure." Maybe something like that?
Or maybe it's not good advice....check with others too, since I'm maybe too close to this issue.
We'll learn together.
Hops
