Hello,
Psychology Today has a search engine (
https://www.psychologytoday.com/us/therapists) that allows you to filter by location, specializations, type of insurance the therapist takes, etc. It sounds like a trauma informed therapist might be helpful for you.
You mention possible codependency on your part. I have spoken with the mother of a daughter with severe BPD who found Codependents Anonymous (
https://coda.org/) extremely helpful for her own growth and healing. I attended one meeting some time back and did not have the same experience. But each group has its own personality. So it may or may not be useful for you.
You have been through a lot. I wish you the best of luck in your journey towards self-understanding and health.
