Hi thrownforaloop,

I still can't figure out how to deal with the anxiety though. I worry about her boy so much, but feel so very helpless. I'm all the way across the country and feel like moving back would leave me too vulnerable to her cruel behavior.
I don't like worrying that every year or so they'll be bouncing from house to house... .as she burns through men, jobs and inability to pay rent. And of course, with the chaos, she'll constantly loop back to hitting me up for support... .usually financial, but occasionally emotional. It will never end. It's sickening, really.
I'm sorry to hear that. Anxiety is tough, have you talked to your MD about anxiety? Exercise helps most people with anxiety, the effects from exercise can last for days, just simply going for a walk helps, try calm breathing, there are strategies that can help alleviate anxiety symptoms, anxiety is just our body's natural response to danger but it can interfere with our when the response doesn't shut off.
I hope that writing it down helped you, you can take a look at what you write down when you're worrying and challenge your thoughts, for example "she'll always hit me up for money" what's another way of interpreting that? "If ii set the boundary on myself and say no, I don't have to give her money"
I can understand how distressing that would feel, you're not absorbed certain how the future holds out, your ex always managed to get by? A pwBPD have a dependency on others with things that they really should be doing for themselves, she has to want to help herself, moving closer to her isn't going to help, trying to fix things is not a long term solution.
Try writing things down, then challenge your thoughts. I hope that helps.
