Hello 40NotFeelingWell: Thanks for sharing your experiences.

I see this is your first post here on PC. So... welcome to Psych Central.

(I do believe you have posted in the correct forum by the way.)
I'm sorry I don't think there's a lot I can say about this. As you mentioned, therapy is an option... perhaps the best option for delving into all of this. Perhaps other PC members will have some book suggestions or insights they can share. In your title you asked if growing up with a mother who had BPD shaped you & I believe that is certainly the case. One additional forum, here on PC, that may be of interest to you would be the Childhood Emotional Neglect forum. Here's a link:

You also mentioned thinking you are, perhaps, as sex addict. Here's a link to an article, from Psych Central's archives, on that subject. The article provides links to a number of additional articles on the subject:
What Is Sexual Addiction?
And then here are links to 2 articles on growing with the a mother who has BPD plus 1 on the consequences of having an emotionally detached parent:
A Box Full of Darkness: Growing Up in the Shadow of BPD
Coming to Terms with a Mother with BPD | Dialectical Behavior Therapy Understood
7 Consequences of Having an Emotionally Detached Parent | Caregivers, Family & Friends
I hope you find PC to be of benefit.
