Books recs / self destructive / addiction / dark

Hello fellow readers. I might have specific ask but I wonder if there are any wlw books out there that:

• Focuses on wlw relationship

• One of the main characters is struggling with drug abuse/addiction — the darker and more real the better (TW: addiction, relapse, self-destruction)

• There’s a D/s or BDSM dynamic • Possessive vibes

• And at some point, one of the main characters is helping the other through the addiction

• Also… smutty as hell !!!

Basically dark, intense, emotional, messy, sexy, not afraid to go to uncomfortable places. If you’ve read anything like this — please tell me. Thanks!
