No substitute for societal changes aimed at reducing the trauma experienced by women and children in a patriarchal system.
Cookie-cutter CBT - ten session to challenge your thinking and behaviours - is not trauma-informed.
Good psychotherapy with someone who understands trauma will support you to look at your thinking and behaviours, but in a context of holding space for your very complex emotions.
Mindfulness can be a way of disassociating from your trauma. Again, it's a single tool, and it has some effectiveness, but it needs to be applied in the context of a warm and skilled practitioner who understands trauma, and who can safely support you to process that trauma.
My personal experience of seeking therapy to deal with childhood abuse and neglect, mirrored in my marriage, is that many of the standard therapies simply did not help. For a long time I thought that was my fault - I was not committed to being helped, I was not good enough at CBT. Engaging with these therapies increased my self-blame and self-hatred, and bedded down even more firmly my low self-esteem.
It was worse when I saw that CBT is, actually, a gold standard treatment. I felt the fault was in me, not in CBT.
What I think now, is that in someone who does not have unresolved trauma, CBT can be helpful for anxiety. In people with unresolved trauma, it can be helpful for anxiety in conjunction with other, more person-centred therapies. Probably after person -centred therapy has started, and a warm, safe therapeutic relationship established.
From a feminist perspective, it's all a bit closing the stable door after the horse has bolted. It's an individualist approach to trauma. The feminist response is preventative, I think. How to stop women like you and me being subject to DV in the first place.
I have no idea whether my feelings on CBT and mindfulness and therapy are actually feminist beyond that. I know psychotherapy does not have feminist roots, but there is a history of feminist psychotherapy. Hopefull someone more schooled in theory can answer you on this.
Otherwise - I think social support can be useful, I think practices which calm the body and bypass the thinking part of the brain can be useful (so things like tai chi, yoga, mindful walking), I think creative activities can be useful (writing/journalling, art etc) and I think establishing an ongoing relationship with a skilled therapist who is warm and available is helpful.
I would support you in turning down CBT and mindfulness programs while you wait for longer-term therapy. Yes, CBT at a population level is probably a cost-effective and evidence based intervention for anxiety, but in the situation you describe, I think your instincts are good. It took me around ten sessions to establish trust with my therapist (an ongoing process) - ten sessions of CBT and I'd be out the door, with any remaining dysfunction up to me to solve with 'practice'.
Sorry this is long and rambling. I hope it was helpful. I bet women with more expertise come along to answer you soon.
