So after reading and hearing psychiatrist speaking, I think my mum has BDP. 
She suffers from chronic depression/anxiety and fibromyalgia, but her behaviours are very strange and she been physically violent before and really exploding to the point we fear that she would hurt us or herself. 

My mum hasn’t been diagnosed before (as far as I’m aware, she never told me) of BPD, she also always says that she does not get enough attention from doctors and not enough help. 

Obviously I didn’t know my mum for half of her life, and while I was younger I couldn’t really tell apart from the arguments and her being physically violent with me (which at the time was normal for her, because that was what parents did to their kids in my country). Could my mum have developed BPD later in her life, from her life experiences and illness? And is there anything I could do to try to figure her out and help her? 

Thank you in advance xx
