Quiet borderline and C-PTSD

I believe I have both. But there's a lot of overlap and it makes me wonde. For example, is my C-PTSD more severe because I had borderline and I saw my father as a good or totally bad and dangerous person? Do I people please because of quiet borderline or because of traumas around when I was 8-9 years old. I know that borderline stems from trauma as well and that I am emotionally like 4 year old kid. It's very difficult for me to understand myself since suffering from C-PTSD, BPD and treatment resistant bipolar 2. Any thoughts?
