Does anybody else feel like they can’t connect with the rest of world because they have such a shit relationship with their mother?

I know BPD people (like me) always like to pass the blame to somebody else, however, sometimes I feel like the relationship with my mother is the main course for my BPD (guess it would make sense as personality disorders start in childhood) 

I feel like the rest of the world has a strong connection to a mother, no matter what their relationship may have been/ be.

I personally feel excluded from the rest of the world because there has never been a connection between me and my mother at all, like since birth. The last time I saw her I think when I was 13 and I’m 25 now
 
I just wanted to know how common it is for people with BPD to not feel related to their family - putting all trauma aside, just focusing on pure connection here

HUGE thanks to anybody that replies and can relate to this!
