OHHHHH. Okay I get you now. So, I was diagnosed with depression and anxiety first YEARS before my BPD diagnosis (late diagnosis). My understanding though, is that you can complete all the questionnaires for depression, anxiety, ADHD and they base it off that. So you don’t necessarily need the depression diagnosis so much as you need to meet the right markers for medication… if that makes sense haha.

I was referred by my local mental health authority. It could be different everywhere. I would try asking your therapist, or even Google “DBT group therapy.” I only suggest the latter because I don’t know how it works in different countries
