Stuck between English lit and economics

Ik it’s very late into year 12 to have this problem but I’m currently doing psychology and sociology alevels (I’m interested in doing forensic psychology at uni) but I just switched from English lit to economics because I found English lit a bit hard ( currently doing Frankenstein and a streetcars named Denise), I wanted to do governance and politics but it was at the same time as my psychology classes, when I joined econ i understood nothing, mainly due to the fact I haven’t done math since year 10 (did my gcse early) and I’ve also never done economics before. Can anyone who has done these subjects give me some advice on what to pick?
