Life outside comfort zone

I'm about to explode because of a person, one of the bosses at work, which is always ironic in a bad way, to tease, to feel superior. I've been obligated to suffer for a month, and now I feel like I explode. I do gym and meditate, but every week this person ruines everything. I'm afraid I ran out violently, I'm trapped because I don't have an alternative, there's only that job now and for next year, I wonder if my life is going to end like this, for a fight, fired and arrested, while the boss continues to enjoy and insult his employees....
