DeeMart, welcome to the forum. I'm so sorry about your daughter.
I think...when we are completely spent and exhausted...we have to step way, way back. It's not forever, but we can't go on like we are.
We have to have a break from the relentless never-ending nature of our DCs. For me, that was a big step.
I finally told my Difficult Child that he could only call me on Saturday mornings between 10 and 11 a.m. and we would talk for 10 minutes. If he called AT ANY OTHER TIME, I would not answer the phone.
He tested me, but finally he stopped calling and texting (not immediately) and he respected that boundary. We had to break the cycle of him hounding me all the time. I was exhausted from it. The key is once you draw that line, stick with it, or we're just teaching them that we don't mean what we say.
Once that cycle was stopped, I was able to set more boundaries. One was that I would drive to the day shelter where he would be (he was homeless) on Fridays, he would get in the car, and we would sit there and talk for about 10 minutes.
I just needed to lay eyes on him. I honestly didn't want to do more than that, because it drove me nuts, listening to his justifications, victim mentality and asking me for things.
We teach people how to treat us. I believe I taught my son, over many years, that if he just kept on, I would cave in. It took me a long, long time to teach him that things had changed.
We can't fix people. We can't even fix people who are very sick and whom we love so much. We want to, but we can't. If they don't want to get help, there is truly nothing we can do.
That is a sad and hard truth to accept. And I know how much you are hurting and how hard it is. Please hang in there and keep posting here. We are here to support and encourage you and to offer ideas.
Warm hugs.
