Welcome bubbalooski 28!

A lot of your post resonated with me, and I will say that, while I'm glad you're here, I'm also sorry that you are dealing with someone who has brought you here. I also don't see that BPD fits my mom perfectly, as there are some of the criteria I don't see. However, I've also realized that the label doesn't matter so much. Think of it as a starting place. If you read the books or the resources and suddenly had a sense of clarity, then go with it. What matters is healing yourself--not treating your mom. Diagnosing her is the job of a professional, so don't stress about that part.
My mom is also a devout Christian, and I too think that faith has helped her with certain aspects of her BPD over the years, such as intense feelings of loneliness or unstable self. I think that without her faith, she would be in a much worse place. I would count that as a blessing for her, and really all of us. My mom does many similar things, such as talking about how she just wants to be in Heaven, she's fine if she dies, blames my dad for basically everything, and uses her faith (which everyone else in my family, including me, shares) as a weapon at times. She also finds all of us siblings to be disappointing at various times, though it is always one at a time. This may not be the screaming/raging behavior that some pwBPD exhibit, but it is no less destructive to her or to anyone dealing with her.
I've spent basically my whole life up till now waging a mental war trying to decide if it is me or my mom, and I have finally come to fully believe that it truly is not me. I feel really bad for her, but it is really not me. My guess is that you struggle with guilt, responsibility, and fear in the same destructive ways that I do, just from what you've described. My best advice to you is to tackle that head on. Don't wait and let it eat you and further steal from your life. I'm so glad that you have a T that can help you with this. One last thing. I know that this can be hard to internalize, but you do NOT owe your mom anything. You are not her spouse, her caretaker, or her guardian. We are normally told to not be selfish, but in this case, I strongly encourage yourself to put YOU first.
