Hello Syringeblacklon, we see you reaching out for support in parenting, which is so commendable.
As you're newer here, you might not have known that this site focuses on people in relationships with a pwBPD (person with BPD or traits). We would hate for this experience to be destabilizing or unhelpful to you, as it is not designed for supporting persons with BPD, as yourself.
That being said, we're so glad you recognize you want more support as you care about your son, who I'm sure is an absolute delight. Try these resources:
NAMI Connection is a free and reputable support group that can meet as frequently as weekly -- check out the description and see if it would be a good fit for you:
https://www.nami.org/Support-Education/Support-Groups/NAMI-ConnectionAs an adoptee, you may have access to adoption agency "post adoption support". Even if the group that facilitated your adoption doesn't offer that kind of support, you could try reaching out to a different group (like Holt International, just as an example) for starters, and say "hey, even though you guys didn't manage my adoption, I see you have post adoption support groups -- would I be eligible, and if not, could you point me to some resources?" Adoption groups will definitely understand the impact of RAD on adult adoptees starting their parenting journey. Start here and see if seems helpful:
