Hi trekchic1701,
Love the moniker
I'd like to join
Libra and welcome you to the group

I agree you are not alone in asking these questions. I come at this from a slightly different angle my Partner has an undiagnosed BPD ex-wife (uBPDxw) and they share 2 daughters. I see behaviors that they have that mirror their mother. Each shows the effects of a dysfunctional mom but neither meet the criteria for BPD (in my humble totally non-professional opinion).
It is completely normal to question what you may have learned from your mother, we all learn from our parents both the good and the bad. Your awareness will only help you work on those places you see as a problem and Therapy will continue to be a helpful tool and we can be here for you too.
How often are you lashing out? Is it frequently? What do you think might be triggering it? How are you reacting afterward?
I like to share tools and information from the site the link below is about DBT but also about mindfulness I thought it might be helpful.
