Hi Tanzinite

Welcome to our online community

The situation with your brother sounds quite tough. It is unfortunate that he seems unwilling to take more steps to deal with his issues.
You are also dealing with your own health problems which makes it even harder for you.
I am glad you are reaching out here for support. Many of our members have BPD family-members, and a lot of us (including myself) have a BPD sibling.
When did your brother's issues start? Was he already exhibiting certain difficult behaviors before he joined the military?
How does your brother generally treat you?
Take care and again, welcome to BPDFamily
