I want to quit now

I have studied pretty much well for the whole year and now my syllabus is complete in every subject except sst. Today i tried studying sst and its all frustrating; too much to remember, too many maps and what not. My brain is exhausted as fuck and nothing is getting into my brain now I have unfortunately developed the attitude that im not even that desperate for scoring high than i was earlier. I feel very low on energy Syllabus is done but pyqs and sample papers, 0, literally 0 I dont know what to do, too much to remember, revise and practice. FML i didnt want this to happen
