Depends.
If my becoming psychotic was the result of a deliberate decision on my part to not take meds, then I am responsible for the consequences. Sort of like how I’m responsible for whatever happens if I drive while intoxicated because it was my decision to put myself in that state in the first place.
If I was to become psychotic through no fault of my own (i.e., not the result of a decision I had made), I would not blame myself for anything that happened while I was ill.
