Perhaps you've recounted it different here but the salient bit for me is what I interpret as yr feelings of unworthiness, not being enough to keep your dad here. Not the stuff about the hair and therapy and feeling jealous about Barbie doll.

I read that as why like how could he miss that? That's what he needs to pick up on. Sometimes if I tell my t a long winded story like that, and hide the message in it, but seem.to place emphasis on a relatively unimportant bit, she'll humour me by responding to the hair etc but then draw it back to the unresolved feelings over yr father's death and we will talk mostly about that. Guilt, responsibility, unworthiness - all that will likely play into yr life now.

Of course everything is easy in hindsight and if the story was recounted as you write he may have got caught up.in the defensiveness about therapy. But then you want a good t that can.pick things up in real time.
