I want to be open. I want to talk. But I literally have no clue what specifically to talk about

I know what I need to work on: abandonment, ex-T, relationships, not depending on professional, getting healthy again (okay this one I don't want to talk about). But I seriously cannot come up with a topic that will dive deeper into my issues. Any advice? I asked my T today for advice and she said she had none

It was a lot longer of a conversation because she's telling me where I can improve on therapy and I'm taking it as I'm doing something wrong, so I flipped out and thought she was going to abandon me like ex-T.
I just feel so stuck and confused. My ex-T would have lead the conversation for me... I miss her.
