Is it possible (financially and time wise) to just say like you feel an extra session ahead of schedule, if she gets an opening? It sounds like you had a lot of important things to process.
If that's not feasible or necessary, I'd say you can try priortizing, but I find it rarely works for me. If there is something really important, like safety recently, then sometimes I will have to FORCE myself on it (if I don't freeze), but usually, I have no control over what "needs" to be talked about in the moment. I have a lot of trouble even initating at all, because as soon as I see T, my mind becomes a jumble of conflicting things that parts of me want to say and then when I try to select one, I get so confused that I just freeze.
There is no harm in just trying to prioritize your discussion and telling her in advance: "I really want to at LEAST address these two topics." Unless they are brief questions that don't involve me giving any input, I have found we can rarely get to more than two topics in a single session lately...I have about five to ten topics come up a week (although as many as half may be past ones that still never got addressed), so it's pretty rare that I feel a sense of "completion" in a session. That said, I'm learning, slowly, that my T will be there for my phone session, then my next office session. I talk to him twice a week. Eventually, if something NEEDS to be talked about, it will still "be there" to talk about. Sometimes things sink below the surface and I worry that they will be lost forever, because my mind makes things go away very easily. It's hard to remember that if they absolutely need to be dealt with, they will surface again eventually, and I don't have a time limit with my therapy to discuss them. I guess this is the pacing T has been trying to get me to do for months.
