How can you distinguish FA attachment and BPD?

I was diagnosed with FA but I can relate way more to BPD. Copendency issues, promiscuity, self-harm (I don't harm myself, but I tend to do things to self-sabotage myself). Severe depression and suicidal thoughts appear everytime I realize that 'abandonment' is taking place. Also hanging out with dangerous people, I don't do this anymore but I was pretty much used to do so. I overreact with rage in intimate relationships and misinterpret what other people say. Again, this patterns are way more consistent during cold times of the year. I had an unstable childhood, my dad died when I was 2. I've been living in 3 different places and I'm 22 🤣 Still planning to move and move, trying hard not to get attached to others.
