I don't know if that's the right question really. How essential is it that you share/ tell everything to your therapist?
I alluded to childhood abuse in my last session and said I would talk about it this week. Now I'm not so sure I want to. I've had five helpful sessions so far (about my non-relationship with my now-deceased father mostly), but I suppose this issue is also important. I didn't think it affected me right now though. I thought I was over it. But it turns out that I never really deal with things, I just pretend they never happened/ pretend they don't matter - a pattern learned in childhood and endlessly repeated. I guess this is the same thing.
But it's all so sketchy. I've thought about therapy/ disclosure in the past, but can't remember (maybe haven't tried) enough detail to make it concrete. I'm not sure I really want to know...
