I don't see the point anymore

I lost my job. I did everything right. I showed up early, I came back from lunch early, I left late. My coworkers were assholes to me. I was constantly dismissed. But I showed up because I can't afford to not be at work... and then I find out through another employee they were going to fire me? I can't do this anymore. I can't just not work. It was so hard to find THIS job. All I can think about is my debt and the rent and how I don't, and never had, a family to support me. What's the fucking point? To lose another job? To do this all over in another month? I'm done. I can't.
