hi RI1442
i wouldnt be so quick to rule out dbt as something for kids with "serious issues like self harm/bpd" it sounds like your issue is pretty serious as well as much as it is negatively impacting your life. i do not have bpd but took dbt for my anxiety issues and it was the best thing i ever did. dbt focus is about learning how to manage your emotions, one is not being able to manage anxiety.
