Trigger Warning - Domestic Abuse

to my therapist and to me it’s clear that my responsibility related OCD was drilled in to me through domestic abuse, now I’m stuck living with it. I take medication which helps me greatly, but I get so stuck in rutts of extreme depression and obsessing. don’t know where to start to I try better to manage the compulsions or to heal from the triggers, how do I heal the triggers when compulsions cause flashbacks. Does anyone have experience with this. I’m lost for where to turn.
