Hi Crivvit
I am very sorry that your mother is so sick now. It's never easy when a close family-member has a serious illness.
Has your mother been officially diagnosed with BPD? Has she ever gotten any targeted treatment or therapy for her mental health issues?
I am glad you have a support network in the form of your therapist and husband, that can really help when dealing with a BPD parent.
Guilt is something many children of BPD parents often struggle with. Based on your post it seems your mother might be using things such as obligation and guilt to try to get you to behave in a certain way. Would you say this is an accurate assessment? If so, you might find the following article interesting:

fear, obligation or guilt ("FOG" are the transactional dynamics at play between the controller and the person being controlled. Understanding these dynamics are useful to anyone trying to extricate themselves from the controlling behavior by another person and deal with their own compulsions to do things that are uncomfortable, undesirable, burdensome, or self-sacrificing for others.
