Hi, I'm (22f) pretty new to my job, but I already wanna quit because it's giving me anxiety and it's not making me happy anymore.

Let's start with the place I work at. A local architectural firm with good customer reviews because of its work quality, but the salary is below minimum wage. I applied here because of its quality works, making me think that I will really learn something from it. Despite of its long travel distance from my home, I still took the risk. I work in the office since I have no work experience at all. The ones with experience are placed to the site. The first few weeks were good, but the moment I was working there for more than a month, I felt the pressure. I feel like he's giving such huge responsibilities to his apprentices. I also slowly saw how my boss treats his staff (carpenters, labors, etc.) in the site. He pays them below minimum wage too and says hurtful words to them if they did something wrong. It also goes to my colleagues in the office. My officemates say that our boss is just pushing us to our limits and see what we can do. But I don't know if his method would be effective to me since he'll say things and yell to his staff like, "Are you stupid?", "Is that all you can do?"  or worse, "You wouldn't be an architect if you're like that" despite doing your best. I also observed that he backstabs some of his past employees and other architects in our area. My boss haven't scolded me yet, but I'm really scared to hear those words directed to me. Past employees also left because of how he treats his staff. But to be fair, he's actually good with his art. He also jokes around because he doesnt want the workplace to be really toxic. I did learn a lot of things from him in the span of 3 months, but for some reason it's not making me happy anymore and I think my admiration for him is slowly disappearing because he is making me anxious. Oh, I also have a feeling where he guilt-trips his staff  when they'd want to leave because he'd say, "It's up to you, but it would be a really big hassle to find a replacement if one of you would go since I already trained you to do the job. All the training that I did to you would be put to waste." To be honest, if ever i would quit my job, I wouldnt really feel bad for my boss, I'd actually feel bad for my underpaid officemates because the workload is just too heavy and we're really understaffed. It's also hard to find a replacement because of the firm's location. 

I am also a working student, but i only have three subjects left and we meet online. I also work an average of 10 hours a day because deadlines are need to be met. Because of this, i barely have time for myself and my family. 


Bottomline: I just really want to leave my job, but I don't know how.
