Please give me some advice! Teachers?

I’m at the point where my job is making me sick. I’ve been applying for jobs, but it is complicated because my husband is unemployed right now so we rely on my salary and insurance. This year in particular has been exceptionally rough. I am so stressed and overwhelmed I’m sick with vomiting, severe stomach pains, and panic attacks. Recently there was an incident where a student got verbally aggressive with me, calling me a white motherf**ker, mocking me, and making rude comments. This student has already been moved 3 times from classes and was even moved from another class of mine because he had a lighter and tried to burn a girl’s hair. I’ve told administrators I’m uncomfortable and don’t feel safe around this student. The response is that he can’t be moved anywhere. Today we had a 3 hour lockdown and nothing was communicated the entire time. Two students ended up being arrested. I just wish I never had to step into that building again. I don’t know what to do. :’( I feel like my soul is broken at this point.

Edit: Husband has been actively looking for work.
