Perhaps ask yourself why you sought out therapy in the first place. What your goals were and talk to your T about wanting to focus on the present symptoms you’re having more than the past since it makes you ruminate at home.
I have a lot of childhood trauma my T thinks I need to work on, some of it I agree, some I don’t and I tell her so, she doesn’t believe me i think.
But I find my most helpful sessions are those focusing on my struggles today! And sure, they’re often linked to something further back but and I don’t mind discussing if she asks but otherwise try to steer things back to the present. After all, it’s those things that affect my daily life now, even if the root was when I was 5 or something.

A break might help also, or there’s nothing stopping your from quitting. It’s completely up to you. Maybe now is not the time, or you could manage better without? Everyone is different.
