Even if you do have full blown BPD, Hope, it has a very good prognosis with the right therapies like DBT and schema therapy. A lot of people with BPD develop it from complex trauma like you've experienced.

I agree that CPTSD is similar in some areas with BPD (and BPD + PTSD is common) alongside some key differences, but what matters is not the label but how your pdoc/T is going to approach treating the underlying traumas fuelling your symptoms.
