Is "hospice caregiver support online" a thing?

I'm blocked from being able to see my old therapist, and have zero motivation to try to battle my insurance company to get in to see a new one. Husband is transitioning from palliative care to hospice care this week. I'm really struggling with handling my emotions, (BPD, so, emotionally dysregulated on my best day) but not about the hospice stuff, strangely enough. It's my emotions, in regards to attitudes and emotions from friends and family that have me ready to scream.

The hospice team is coming Tuesday, and I know they have some sort of support available....but I'm concerned that it will be during visits only....where I won't really feel like I can be as open as I would need to be, because, hubby is right there, and he can't handle me when I'm dysregulated. Also, concerned that with the addition of CPTSD and BPD, they won't really "get" where I'm coming from.

So, does anybody here know of anyplace online, that would offer good support for hospice caregiver issues? Or should I deep dive into BPD resources, even though my situation is, well, situation specific? Or is this a situation where I need to hit this on both fronts - caregiver support AND BPD support?
