Can you tell your T about your family; thinking more about parents, siblings, growing up, relationships with them now you are older etc. (although where applicable also about children, spouses etc.) ? (that's the can)

The second part is how?

I can talk about me, what I'm thinking, how I relate to things, my experiences but when it comes to discussing family most of the time I freeze and can't talk because to say anything at all feels like a massive betrayal and not something to be shared with anyone else, it feels like to do so would be doing something wrong no matter what was said (positive as well as negative). I have talked a bit about it with my T, but it was so hard and continues to be difficult
