Hi Raven913

I am glad you are reaching out here for support and advice.
BPD is quite a challenging disorder. How long has your brother been exhibiting behaviors you now believe are the result of BPD?
Do you feel like your brother has ever shown any insights in his own behaviors and how damaging they might be? Do you feel like he acknowledges that there might be something going on with him causing him to act this way?
Take care and welcome to our online community
