She was diagnosed with BPD at an early age

While she is still a minor and her parents don't have enough cash for therapy

She started taking drugs as a form of self medication (Xanax &amp; Vicodin)
Now that her supply has run out she's trying to get her hands on some more drugs

She was telling me she was gonna save up this year so she could pay for the therapy herself, now I'm worried she'll breakdown and just grab some more drugs

I have a slight understanding of bpd, 
Anyone who could help me with this?
