Yeah, I hope it works out for you. I know that some people with depression have issues finding a med that works, then their pdoc prescribes a med like Latuda or Lamictal, even though they're technically "bipolar" meds. So, that might be an option to consider as well.

Have you thought about bipolar? You mentioned BPD which has similar-ish symptoms. So, you could always try a bipolar med if you get tired of trying antidepressants. Latuda takes anywhere from 3 days to a week to work. It's pretty fast.
