Welcome Morning Glory, you're in the right place. This is a group that really gets "dealing with" people with BPD and BPD-type traits and behaviors.
I'm so sorry you feel sad and alone on Christmas Eve. Here's a welcoming hug for you

I just want you to know you're not alone -- folks will be here over the next few days to start walking with you.
Whenever you feel ready, please share more about the challenges you're facing, and we'll talk with you about some ideas.
Merry Christmas and welcome once again;
