@mountainskies You might want to see if there is a skilled DBT therapist in the area you live. Google DBT or Marsha Linehan or the Linehan Institute. DBT offers evidence-based skills training for all types of people struggling with disorders of emotional regulation (no matter the root cause or exact nature).
In the hands of a skilled DBT practitioner, you will learn the concrete skills you seek and as they say in DBT circles, you’ll “Build a Life Worth Living”.
We were fortunate to stumble upon an amazing, effective DBT therapist. The therapist gave us the name of a psychiatrist, who has been managing the meds. The two practitioners work well together.
As parents, our kid needed our help knocking on doors and not stopping until we had assembled the right team. And, we help by paying for it, & prioritizing it. Neither practitioner takes insurance. Our kid getting the help she needs, and getting stable/well is the most important thing.
Good luck and good health to you!
