SAWE - you seem to have touched on a lot of scary and deep issues; I can even hear this in your post.
I would maybe journal about these feelings - start with whatever you find easiest... Then maybe write it out for T to read. Start slow
I'm not sure if your T formally annouced that you were going to start focusing on these issues, but maybe you need to have a discussion on where your therapy is going from here.
It sounds like you have gotten through crisis management, and are now looking for more long-term solutions; this is an exciting time :-)
