Hi Betsey123, welcome to the forum

No apologies needed about feeling desperate. I was one of those desperate members, too, when I joined (to get support for coping with my H's kids' mom, who has many BPD traits).
Taking space for yourself, so everyone can calm down, makes sense. There must be some deeply overwhelming things going on to feel like there's no resolution.
What would you say is the biggest challenge facing your family right now?
