My new job is making me depressed

I recently started a new job, and feel myself feeling really down when i’m there and before I have to go in. I’ve never felt like this before when starting a new job, it’s all new to me but everything just makes me feel down when i’m there. I don’t really gel with any of my coworkers as a lot of them are way older than me, I just sit at my desk miserable all day. I hate this and I want to find something I enjoy but it feels impossible
