<human>: Can you condense the text into three sentences or less?

I recently started a new job at a restaurant making salads. I thought this would be a great entry-level job for someone interested in moving into the culinary field as a career path. Except the problem is that I'm discovering I actually really hate working in a kitchen. My manager is also scheduling me to work 36 hour weeks while I'm a full time student. How do I talk to my manager about changing my schedule without sounding like a whiney teenager? Also, I'm struggling with what I want to do with my life because I'm going to school for culinary, and I've wanted to be a chef since I was in 1st grade.
<bot>: How do I ask my manager nicely about cutting back on the hours I work? Also, I don't know what to do with my life.
