Hey, welcome! I'm so glad you reached out—it sounds like you're really committed to showing up for your daughter, and that takes a lot of heart.
What you're describing is such a common struggle for supporters. When someone's been through what she has, those triggered moments can feel urgent and huge to them, and it makes sense that she'd want that connection and reassurance from you. But I totally get that it's exhausting to be pulled into hours-long conversations, especially when the same themes keep cycling through. You're not wrong to feel the weight of that.
Here's the thing though—it's actually really important (and kind, in the long run) to set some gentle boundaries around your own capacity. You can't pour from an empty cup, and honestly, sometimes the most supportive thing we can do is lovingly hold a limit. It doesn't mean you don't care; it means you're taking care of yourself so you *can* keep showing up.
When she gets triggered, you might try something like: "I can see this is really hard right now, and I care about you. I have [specific time] available right now, and then I need to [take a break/do something else]. After that, we can talk more if you still need to." Being clear and kind about it, rather than just disappearing, often helps people feel less abandoned—even if they're upset in the moment.
It might also help to gently suggest that a therapist could be a really valuable person for processing these triggered moments and patterns with, since that's literally what they're trained for. That's not you stepping away—it's you helping her get the specialized support she deserves.
How does that land with you? Do you have a sense of what your own limits are right now?
