Hi emily333 and a warm

You'll find yourself in good company with other members who have started having the realization that things weren't always as they seemed in their families. Like you said, sometimes we learn information or have insights that "break" the old ways we saw our parents.
What are some of the traits or behaviors you saw in your mom that led you to suspect BPD?
And it sounds like you are realizing that your dad also had some unhealthy approaches? What did that look like?
...
My husband's kids' mom has many BPD-type traits and behaviors, and remarried to someone with many NPD-type traits and behaviors. While the kids idealized their mom and stepdad for many years, our oldest (18) is now having some realizations about their behavior and wants to get therapy. You're definitely not alone in going through that process

It makes sense, too, that you love your parents and miss them -- I wonder if you miss who they should've, or could've been, or who they were "when things were good"?
...
We have a great book section with reviews, including this one on
Surviving a Borderline Parent, by Kim Roth & Freda B. Friedman, Ph.D. Check it out when you have a moment and let us know if anything in that review hits home for you?
In the meantime, settle in, feel free to read others' threads, and post whenever and about whatever feels workable to you.
Glad we can be here for you;
