Very raw but also very powerful. I really liked how you used the visuals to support and complement the text (the endless stairs / halls, the split-second flashbacks to previous scenes of abuse, etc). The dialogue manages to convey a lot of information (character's backstories and mannerisms) with relatively little text, a sort of "economic" storytelling (word-count wise) that complemented with the visuals and audio really hits the spot for me.
If this is partly or fully autobiographical then I sincerely hope you're doing better now, but regardless, I feel like you've tackled the subject matter with a lot of nuance and respect. Great work!
