advice on therapists?

i'm palestinian, afab and nb/trans, disabled, and adhd (most likely autistic as well)

my therapist has helped me with emotional regulation and guided me when it came to medicating (my feelings around it, not what to take) so my emotions have been a lot easier to control.

i really value her as a place for emotional release and guidance. but i sometimes feel confused as to what therapy is supposed to be. i don't feel like how i show up in the world and my relationships are explored well in therapy, and i also wonder if the intersectional issues i struggle with go over her head (she's black and christian, although ive never felt she dismissed me or invalidated my identity)

I also don't know how much of trauma we should talk about. i've never gotten to sharing with her things that happened to me as a child, or if im supposed to share them. she is a trauma therapist but ive felt like our sessions are slightly just talk therapy. and i'm really sick of these flashbacks and disgusting thoughts that come with the territory of being sexually abused as a child. not to mention being raised by extremely emotionally immature parents and the ramifications of me being disabled and therefor unable to move out of their house (it's a nice house and my pets are here at least). (sleep paralysis and nightmares are gone though! might be meds...)

i don't know if im doing things correctly, and therapy is too expensive. i dont know how to structure it?
