It sounds like you are indeed doing what you can to better yourself. This is a guess on my part, but you may be a type of client who, on a good day, can come across as being more stable than is really true deep down. It does you no good to have your issues minimized. So make the most of the 12 sessions and use the time to convey the depth and extent of the effect your psychological issues have on you. They aren't going to get solved in 12 sessions. At least get the seriousness appreciated. That might be the most you get accomplished in 12 sessions. And that is a lot. Scoring high on the mania assessment is significant. Same with the dissociation screen.

It sounds like you take a lot of responsibility for your part in working toward recovery. They already see that and have commended you for your mood tracking and journaling. That doesn't mean you don't need some serious help. Again, it is important that they don't underestimate that.

Regarding the suggestions made about your father: The only person who can tell your story is you. But, sometimes, the professionals will jump the gun and think that they have figured out more than they are in a position to know. I only say this because it has happened to me and made me feel frustrated. It is true that a person will very often not recognize certain things about their own history. That is probably true of everybody walking the earth. That doesn't mean you aren't a competent "historian" regarding the main facts of what happened. Some people are in serious denial about some things and need help with that. Maybe that applies to you . . . maybe not. Sometimes, we underestimate how we got impacted by this, or by that. So it's good to listen to how our story sounds to someone else. At the same time, I draw the line on anyone telling me a version of things that came more out of their head than out of what I lived through. And it does happen. Well, to me, at least, more than once. I think your boyfriend's response was reasonable. I don't think he was necessarily implying things about your father. He just said he he doesn't know, and that's what it boils down to - he doesn't know because he wasn't there. It's not that he is saying he doesn't believe you about your father. It sounds like, maybe, he doesn't want to influence what the story should be, but leave you to further explore that with the professional help you are getting. The truth is never simple. You have limited time to get your story across which, unfortunately, may mean you need to delve into it deeper and with more concrete examples than feels okay to be thinking about. You will have emotional support from the therapist while going through this. Just be sure and let the T know to what degree this is stressing you out. Let the pdoc know also.
