Being bullied at work?

Maybe I’m exaggerating or maybe I’m not. I currently started a job doing food service and I find myself constantly being excluded, picked on, yelled at, etc by coworkers, my manager, and customers. No one gets this same treatment but me and I’m growing tired of it. I just wanna quit but I’ll have no money coming in. People always tell me I mess everything up and I try my best. What do I do? I’ve tried speaking up for myself but the same thing happens every day. I come home with migraines every single day from work. I think it’s taking a toll on me.
