Hi Mom,
I really feel for you. Sadly, estrangement is very common with BPD. But my guess is that your daughter will reach out again soon enough, typically when she wants some help.
Look, if your daughter didn't want to associate with you, she wouldn't have messaged you at all. I think she wants to punish you right now, in a misguided attempt to make her feel better. In my experience, this sort of behavior has nothing to do with you; rather, it's typically a sign that your daughter is stressed out right now. Because she can't handle the stress very well, she's lashing out at you. It looks like she's trying to control you, too, perhaps in a vain attempt to reclaim some control in her own life.
My advice is not to take down the pictures from Facebook. What you do on Facebook is your business. If she doesn't want to see you on Facebook, she can stop looking at you on Facebook. If you do her bidding, especially in the context of a manipulative, angry request (i.e. not a rational one about safety or privacy), my guess is that it won't solve her problem one bit, because the problem isn't about you sharing family pictures. By agreeing to her irrational requests, you'd be incentivizing her mean-spirited behavior. I'd advise not to increase her incentives for lashing out with meanness.
I think your mom said exactly the right thing--she doesn't want to be in the middle. She didn't say, OK, I'll agree to an irrational request to alienate a granddaughter from grandma. Kudos to your mom! She refused to be triangulated and manipulated, even if it hurt her a lot.
Now I know that probably doesn't make you feel much better. Please know that you are not to blame for BPD. A mantra here is the three Cs--you didn't cause it, you can't control it and you can't cure it. That might help alleviate some of the guilt.
