I hate my job

So I have an entry level government job because I wanted to get into the legal field. I thought I wanted to get into law and possibly sexual assault victim advocacy, but my current job is ruining me. I work in a very small office and the people are toxic and negative. The work is monotonous and boring, while the customers are angry and upset the majority of the time. I want to find somewhere else but thinking about having to quit after being there less than a year causes so much anxiety. And I feel as though I’ve lost all motivation and direction. I want to be professional but this job is sucking all life and motivation out of me. Any advice to be help is appreciated.
