i need advice 😞

so i started a really great job when I was 4 months pregnant, i left once I had my baby but the manager really wanted me to come back once I was ready so I decided to. she offered me a position as her assitant, great pay. unfortunately some of my coworkers were threatened and upset. i stupidly left my checkstub out on my desk. someone saw how much i get paid and I apparently started "a war" as my boss put it. im seriously debating on leaving. work was already uncomfortable to begin with and now this makes me dread even being there. any advice?
