first look at your expenses and see where you can save a little bit to help yourself out a little bit. then talk to a supervisor about your situation and see if you can get some sort of raise. if you still are barely getting by, you might have to look into a new better paying job or pick up a side hustle
if there is a hobby that you already do that you can find a way to monetize that would be the easiest and something you are more likely to want to do rather than get burnt out after 60+ hour work weeks. but if not i have done transcription through transcribeme. its pretty easy just listening to audio and typing out what it says. you could also try doordash or something like that
