My job is making my cry so bas

I have a job as a call center agent I am not American and Americans are so mean to me they are so rude and I genuinely dislike them they have been telling me so many racist things thanks to my agent and my manager just keeps telling me that I don't have to take it personal but i still feel so sad I wanna cry because I feel like nobody is supporting me I don't wanna come back tomorrow I need to vent
